You mean Window.Read? Yes, that will block the entire process waiting
for input and no Gambas timers will fire. You can either use the Timeout
argument to Window.Read (in milliseconds) to get out of that every once
in a while or handle input using the Window_Read events, which I strongly
recommend.

There is no specific API for keyboard shortcuts. I meant you just grab
input (either from Window.Read or from the Read event, whatever model
your application uses) and interpret e.g. "K" as "kill that process now".
In most applications you have some dispatch table of keystrokes to
program actions already.

fbv is a tiny program you can find on github. It seems to have strictly
less features than fbi and probably works the same for all it does.
I have no idea if it's still maintained or if it needs maintenance.
It can't read PDFs. I had fb... -pdf for that.
