This reminds me of a problem I face. I write documents in LaTeX all the time, and my preferred text editor is vim. In vim, CTRL-W will remove the last word in insert mode. This has become second nature to me, since I frequently find it faster to retype a whole word than to perform the correct number of backspaces to correct a typo midway.

What this really means is that I close browser windows with great frequency whenever I'm typing something and make a typo, and hit CTRL-W.

I have the same issue with screen sessions. I use Ctrl-a to move to the beginning of the line (an Emacs shortcut, also implemented in lots of shells), but screen's default command prefix is Ctrl-a. Of course, that one's simple to change.

Ctrl-a Ctrl-k in Emacs moves to the beginning of the line and then erases the line. In screen, that key combination kills the current window! At some point, screen added a "Really kill this window [y/n]" which was a terrific enhancement...

Ha, I don't remember running into that exactly. I have found several lines in my local text editor where I type "a" at the beginning because I mistakenly think I'm in screen, so I type "Ctrl-a a" instead of just "Ctrl-a".

Change screen's hotkey to something else. I like Ctrl-b.

Or accidentally clearing a web form that you painstakingly filled out because of ESC muscle memory. :(

What about attempting CTRL+Z directly after clearing it? It might undo your clear.

Taiga does this. Hate it.

The Lazarus Form Recovery addon, recommended by a dead comment below, looks really good - compatible with both Firefox and Chrome.

I do this all the time. I also accidentally try to save web pages with cmd+s constantly.

You could deactivate the shortcut on that page (or everywhere) with Greasemonkey.

Disabling it when forms have focus would be useful.

But this makes it a real pain to close a tab.

Btw, to delete a single word on OS X, alt + backspace. For Windows, ctrl + backspace.

…and on a Mac, to delete to the start of the line, type CMD + backspace. I started using this shortcut, and the parent one, about two weeks ago. They are just now becoming muscle memory, and I find them very useful.

FYI, in OSX a lot of emacs/shell shortcuts work in textboxes/-fields too. e.g., ctrl-a, ctrl-e, and ctrl-k respectively for beginning of line, end of line and deleting to end of line.

You should use pentadactyl then ;) Close browser windows with :t, Ctrl-w does nothing, clicking in a textarea and doing Ctrl-i opens a gvim window where you can edit your text properly. And much more.

As another option, Vimperator also allows vim like editing in textareas with Ctrl+t and supports Firefox >30

Why can't we rebind this key to another key? Why not make CTRL+Q or CTRL+B remove the last word.

Something which really grinds my gears is when software has non-rebindable hotkeys. Why are keybinds hardcoded? We can change our controls in games from WASD to ESDF. Why can't we change our copy key in Windows from CTRL+C to CTRL+L, without using 3rd party software?

Having written my own applications on occasion, I know this isn't that difficult. So why is it so uncommon?

I guess, this is often not prioritized because the majority wouldn't use the configurable keybindings.

For what it's worth: I use AutoHotkey (on Windows) for configuring system wide shortcuts.

also control + q would quit many sane applications

Another hotkey we could rebind! How about we change it to Alt+Q?

At least in vim, you can remap just about anything that you want to.

The reason the feature doesn't get included as often is because of exactly this. Even someone who could make use of the feature, and is annoyed by the current keybindings, doesn't take advantage of re-binding. The reason it is available on video games, on the other hand, is because its necessary for controller support, which a large enough portion of the video game community uses for it to have high demand.

Rebinding system shortcuts makes life difficult for application developers. They have no idea if they can use CTRL+L for their shortcuts or not.

In-app rebinding also makes life difficult for the developer in the future, because any new feature added may have it's key rebound by some users.

Look at Emacs. Technically users can rebind things, but it's easier to learn the defaults since every other key is already bound to something else.

Generally everything is rebindable internally, but users are only offered compatibility modes with other popular software.

I've played more than one game (Freespace, Tribes, Warframe) that had more than 30 keybinds. Managing keymaps can be challenging, but it's not impossible.

And discussing this reminds me how much of a pain it is. What we need is a system where we set our own defaults in an XML file or some other common format (or use a software tool to do that). Then we can select this keymap when we install applications.

Even more annoying is using virtual box with a linux guest and resetting the VM when you wanted to recall a command (CTRL-r).

Well, I never use right control :)

There's no reason to keep the host key as right control if it causes problems like that. You can set it to something different in VirtualBox's global preferences (Control-G) > Input > Virtual Machine.

Also, you may prefer to run your VMs headless with vboxheadless (man vboxheadless). May save you some time and frustration, and video memory. Then ssh into them by going into the guest settings and forwarding port 22 to a host port (I use 12322).

I even did this during a test running in a browser at school. Luckily it was possible to reopen it and nobody noticed. I've done this so many times that I have some setup always running vim in the background in a tmux session only a keypress away. Super+Shift+v then type <leader>y and paste in the browser.

Thanks for the tip. I have this problem all the time.
