KDE – How to Swap CTRL and ALT Keys

kdekeyboard shortcutskeyboard-layoutlinux

Does anyone know how to swap the Ctrl and Alt keys in KDE?

To me it seem like the Alt key is better positioned to be used more often for stuff like the Ctrl–W or Ctrl–S.

There is no way to press the Ctrl key without taking my fingers off of the home row.

Run setxkbmap -print | xkbcomp -xkb -o original.xkb -.
Then copy original.xkb to switch-LALT-LCTL.xkb. Keep the file original.xkb as a backup, better remove write permission.
Edit switch-LALT-LCTL.xkb in the block xkb_keycodes and exchange the keycodes for LALT and LCTL.
Run xkbcomp switch-LALT-LCTL.xkb $DISPLAY to active your new layout. Run xkbcomp original.xkb $DISPLAY to restore the old one.

These instructions suffice for modification on any level of sophistication. The keyboard description file is just structured text, after all.

Backtick and tilde keys – Why the switch

On US keyboards, ~ is the same as Shift`. From what I can see, it looks like the opposite is the case on EU keyboards, so the functionality is practically the same. Is that incorrect?

Windows – Switch Ctrl and Alt with AutoHotKey without messing up the Alt-Tab switcher

I would like switch Alt and Ctrl because I'm currently a Mac user on Window (with a PC keyboard). All hotkeys on Mac: Cmd+n, Cmd+w ... -> PC: Ctrl+n, Ctrl+w and Cmd got same place as Alt key.

I found a non perfect solution:

Map all letters like that :

LAlt & a::Send {LCtrl Down}{a}{LCtrl Up}
...
LAlt & z::Send {LCtrl Down}{z}{LCtrl Up}
LCtrl & a::Send {LAlt Down}{a}{LAlt Up}
...
LCtrl & z::Send {LAlt Down}{z}{LAlt Up}

And you will keep Alt+Tab and AltGr functional
