Tk Source Code

These keys are present in some old unix keyboards, but more importantly, their keycodes can be mapped to physical keys in modern programmable keyboards.
Using them in Linux is a way to be able to have the same keys for copy/pasting in GUI apps and in terminal apps instead of switching between ctrl-c/ctrl-v and ctrl-shift-c/ctrl-shift-v.

The patches are very short so I am adding them here:

Merged to all branches now

Misled by: [https://github.com/telegramdesktop/tdesktop/issues/5835]

There is no XF86Undo/XF86Redo, it's just Undo/Redo

If we do those 3, I think we should add the Undo and Redo variants as well

Put into a [f8bf4f1a0ec636f8|branch] now

Thanks!
