Customizable hotkeys

[alefith]

It would be great if there was a way to customize hotkeys.
Here's how I see it:
 * Have a about:hotkeys panel, with all actions listed, and already mapped shortcuts shown.
 * Whether these should be modifiable or not is up to the dev community, ideally they'd be.
 * When clicking on a hotkey field, ideally, there would be a capturing hotkey feature, or, before this, an AHK like syntax to define hotkeys (not as complex, something like: CTRL+H means this and MAJ+ALT+END means that...)

 * a restore to default button.
 * Done.

It can't be done with an extension because some function can't be accessed by extensions (I'm actually looking for a way to send tab to other device while browsing with TST.). Anyway, I believe this should boost productivity in a number of ways. You guys are devs, you know keyboards are faster than mice. 😛

edit: Corrected the typos, it's been bugging me for months now😅

[RemapHotkeys]

I need to remove ctrl+shift+w, I have a window with over 1000 tabs, I open and close hundreds of them every day. Today I accidentally pressed shift. Reopening the window froze Firefox for 10 minutes, took 75GB of memory and way more in pagefile, and now each page needs to reload as I switch to that tab.
When trying to remap this shortcut using the extension, it just closes the window with options.
