Re: Terminal command in Kate using an unknown profile?

Kate has a list of programs for which pressing Esc doesn't close the
terminal panel. See the "Terminal" page in settings dialog. It could
be that somehow, for some reason Konsole isn't able to tell what
foreground process is running in the terminal atm and thus Kate just
closes the panel on Esc (IIRC, in flatpak this is an issue). You can
disable this behaviour in the same dialog.

On changing the profile: Right click in the terminal -> Edit
profile... / Switch Profile

A workaround: You can use `Ctrl + [` as an alternative shortcut to Esc.
