Multiline-Mode Switch on Window-Manager conflict

[kajdo]

Hi,

i run gurk in an window manager setup and the switcch to multiline conflicts (and therefore doesn't work) with the key bindings configured

think the issue could be fixed similar to: #108

maybe it would be possible to add ctrl+enter as a second option to do the switch (this key-binding isn't used by gurk and i see in the help screen, that for some functions there are multiple keybindings for the same function)

would help me out a lot

discovered, that [Shift]+[Alt]+[enter] works as a switch to/from multiline mode as well, maybe it should be mentioned on the help screen as well

Actually it would be nice to rework the bindings and allow to configure them.

alt-enter can now be remapped by modifying gurk.toml:

[keybindings.normal]
alt-enter = ""
ctrl-shift-m = "toggle_multiline"
