Characters

Virtual keyboards on phones have built in access for emojis and special character selection. On a desktop, these characters can be harder to find

The app "Characters" will allow you to choose non-standard characters, like emojis, via linux. Had had some difficulty finding a way to do this in the past.

Remap Keys

Sometimes keyboards have a key that gets in the way, or deviates from other keyboard layouts.

Sounds like xmodmap is an old way of mapping keys. As noted in the above thread, those settings don't stick around after a reboot. xbd seems to be the way to go for these.

On my Dell XPS13 laptop, I want to remap the 'pgup' to be 'left' and 'pgdn' to be 'right'.

sudo vi /usr/share/X11/xkb/symbols/pc

sudo vi /usr/share/X11/xkb/symbols/pc

Find:

    key <PGUP> {        [  Prior                ]       };
    key <PGDN> {        [  Next                 ]       };

    key <PGUP> {        [  Prior                ]       };
    key <PGDN> {        [  Next                 ]       };

And change to:

    key <PGUP> {        [  Left                 ]       };
    key <PGDN> {        [  Right                ]       };

    key <PGUP> {        [  Left                 ]       };
    key <PGDN> {        [  Right                ]       };

For mapping the menu key to be a control key on the perixx keyboard:

    modifier_map Control{ Control_L, Control_R, Menu };

    modifier_map Control{ Control_L, Control_R, Menu };

Apply the changes with

setxkbmap us 

setxkbmap us intl

setxkbmap us 

setxkbmap us intl

This sets it up globally. In my case, that's what I want.

Looks like it's also possible to do this on a per user basis:
