Code review comment for lp:~trb143/openlp/bug-892571

I'm still new to this so sorry if my comments don't make much sense.

Rather than disabling keypresses while the slide controller is proccessing an action, would it be possible to somehow queue keypresses and then execute them one at a time afterwards?

Alternatively, could the code that looks up the currently selected service item somehow be delayed if another keypress is currently being processed? I guess that could still lead to multiple keypresses being process out of order though couldn't it?

Not sure if any of those ideas have any merit or not...
