What does “Ctrl + Alt + F12” do?


As others have pointed out, the two words following the cursor are transposed, and the cursor is placed after the words that have been transposed. However, Visual Studio 2010 at least appears to ignore commas and other punctuation when considering "words." One utility of this, then, is that you can reorder something like an enum. For instance,

typedef enum myEnum { ThingOne, ThingThree, ThingTwo };

Put the cursor somewhere near ThingThree and press CtrlShiftT to get:

typedef enum myEnum { ThingOne, ThingTwo, ThingThree };

This could be a good thing if you decide that a different order for your enums is better. You can also use this to help idiot-proof comparisons and/or quickly and easily format them to a better coding standard.

if ( ptr == NULL ) { /* stuff */ }

is considered bad (never mind that having an "if" on its own line is also bad) since you could easily write (or read) "ptr = NULL" by accident. You're better off with

if ( NULL == ptr ) { /*...

Ctrl-Alt-Del, sometimes seen written out as Control-Alt-Delete, is a keyboard command that's usually used to interrupt a function. However, what the keyboard combination accomplishes is unique based on the context in which it's used.

The Ctrl-Alt-Del keyboard combination is usually talked about within the context of the Windows operating system even though others do use the shortcut for different things.

Ctrl-Alt-Del is executed by holding down the Ctrl and Alt keys together, and then pressing the Del key.

Note: The Ctrl-Alt-Del keyboard command is also sometimes written with pluses instead of minuses, as in Ctrl+Alt+Del or Control+Alt+Delete. It's also referred to as the "three-finger salute."

How Ctrl-Alt-Del Can Be Used

If Ctrl-Alt-Del is executed before Windows is to a point where it can intercept the command, BIOS will simply restart the computer. Ctrl-Alt-Del might also restart the computer while in Windows if Windows is locked-up in a...

In a personal computer with the Windows operating system, Ctrl-Alt-Delete is the combination of keyboard keys that the computer user can press at the same time to terminate an application task or to reboot the operating system (have it shut down and restart itself). In Windows 95 or any later systems, Ctrl-Alt-Delete brings up a window that allows a user to see the status of all currently running programs and to terminate any of them, and also offers the options of shutting down, restarting, and so on (the specific options vary slightly with the particular version of windows). In Windows 95 or 98, if Ctrl-Alt-Delete is pressed a second time or twice in a row quickly, the operating system closes all programs that are running and then restarts.

SuSE 12.3 (Linux 3.7.10-1.11-desktop)
AMD Athlon Dual Core (64 bits)
KDE 4.10.2 "release 1"
Available updates for SuSE 12.3 applied (zypper).


Power on.
Login User1
Click lock screen -> switch user -> create new session
Login User2

At this moment it's random whether ctrl-alt-F7 or
ctrl-alt-F8 will take me back to User1. However, the roles
of F7 and F8 stays the same until reboot.

Logging out first User2, then User1 and logging in again in the
same sequence as above does not change anything.

The roles of F7 and F8 _may_ change after logout+reboot.
Connect to User2
Click Leave -> Logout
this takes me back to User1
Click Leave -> turnoff computer (or restart computer).

This is one of those jokes people play on each other -- it's in the same category with squirting flowers and exploding cigars. This joke works on machines running the Windows operating system because Windows happens to define certain keystrokes that work the same way in all applications. Just about everyone knows that Alt+Ctrl+Del interrupts the operating system, but most people don't know that Alt+F4 closes the current window. So if you had pressed Alt+F4 while playing a game, the game window would have closed.

It turns out there are several other handy keystrokes like that built into Windows. For example, Ctrl+Esc will pop up the Start menu, Alt+Esc will bring the next window to the foreground, and Alt+Tab or Alt+Shift+Tab will let you cycle through all available windows and jump to the one you select.

On keyboards that have the little "Windows" key (let's call it WK here) down near the space bar, you probably know that you can press that key to open the Start...

I put together a glossary of common shortcuts used by a wide range of programs. This is not supposed to be a complete list but rather a good set of guidelines for software developers who are trying to add shortcuts to their applications.

Many of these shortcuts have been made popular by office while others have been adopted by Adobe, Macromedia, Intuit and others.

General Editing Applications

CTRL+A – Select All text or all objects CTRL+B – Bold the currently selected text CTRL+C – Copy the currently selected text or object CTRL+D – Add the current site to favorites, open fonts dialog in text
applications CTRL+E – Centers the currently selected text CTRL+F – Opens the Find window to search or find text, Forward email CTRL+G – Open the Goto window to go to a line of text or a section CTRL+H – Opens the Replace window allowing you to search and replace, Hide tools CTRL+I – Italicize the currently selected text CTRL+J – Justify the currently selected text...

I'm unable to return to the GUI with Ctrl-Alt-F7 (or any of the 12 function keys). I have some unsaved work and I don't want to lose them. Are there any other key combinations that will allow me to switch back?

Here is what I did:

I pressed Ctrl-Alt-F1 and it showed a text-based login screen as usual Then I pressed Ctrl-Alt-F7 and it showed a screen full of text (I can't remember what they were) Then I pressed Ctrl-Alt-F8 and it showed log messages that resembles /var/log/messages. Some entries are from automount, some from sendmail, and none are errors. Pressing any of the Ctrl-Alt-Fn combinations now has no effect. The cap-lock and num-lock LED no longer respond to their corresponding keys. I can use the mouse to highlight the text on the screen, but nothing else.

Any idea what happened?

I can still login to the system via SSH. GUI applications that I was using (e.g. opera) are still running and consuming tiny amounts of CPU as usual, as reported by top. Is...

Every laptop, or rather every keyboard comes with a set of Function Keys which cater to special functions. And if you know how to use them optimally you might just enjoy using the keyboard. Though F1 through F12 have some default primary and secondary (in combination to the Fn key) features, they can be used well in combination with keys like Ctrl and Alt.

Today GT takes pleasure in listing down the common as well as the best uses of these amazing set of keys. Now, in many keyboards each of these keys will have additional set of functions like multimedia, sleep/wake et al. We won’t be talking about that here. We will talk about how to generally use them across browsers, Windows and mainly MS Office. Here we go.


Almost every program comes with a help or support menu and pressing F1 while on the program brings up the help menu instantly.F1 with the Windows key, however, shows up Windows Help and Support.


On Windows Explorer F2 lets you quickly...

RetroPie and Raspberry Pi PIXEL Desktop - Andrew Oakley



Skip to: How and why does this work? - an explanation of Linux TTY consoles

In Linux, there's always more than one way to do it. RetroPie is a wonderful set of scripts and skins for EmulationStation, a collection of retro computer and video game emulators. By far the easiest way of running RetroPie is to flash their ready-made image to a memory card, but what if you want to have both RetroPie and Raspbian Pixel on the same card? Well, NOOBS and BerryBoot will both support multiple operating system partitions on a single card.

I don't want that. I want to have a RetroPie icon in my PIXEL menu under "Games".

What I wanted to achieve, was to have a single Raspbian operating system running from a single partition (plus /boot) and be able to boot to the PIXEL desktop, then be able to run RetroPie as if it were any other desktop application. And that's where it gets complicated,...

Most Windows computer users need to adjust the screen brightness of their laptop or desktop computer monitor at some point. However, brightness settings are different, depending on what you have (desktop or laptop) and which graphic card you have (AMD, nVidia or something else).

How to Adjust Screen Brightness on a Desktop Windows computer

Regardless of which version of Windows you have (Windows XP, Vista, Windows 7 or Windows 8) if you use a Desktop computer, to change brightness from the Windows settings, you need to access monitor on-screen menu (literally a button on the monitor), then from there navigate to brightness/contrast section and set it up according to your preferences.

You could alternatively setup brightness from the graphic card control panel (eg. nVidia Control Panel or AMD control panel). To access it, right click on a desktop and pick nVidia Control Panel, AMD Control Panel (this depends on the manufacturer settings of your graphic...
