Hi,

while I figured out that I can open a contact's message history by
pressing Space instead of Enter, I haven't found a way to return to the
Contacts list by keyboard. I would have assumed "Escape" as it's common
and e.g. works fine in Telegram Desktop as packaged in Debian as
well. Same counts for when trying to return from contact details to the
contact's message history. Typing "Escape" should generally be
equivalent to clicking that "<" button.

More generally said: Kaidan seems not very usable without a mouse,
trackball or touchscreen, i.e. navigating within the application with
just the keyboard does work only in a few places. IMHO, Kaidan would
definitely benefit from more keyboard bindings.
