Page up/down and move execution to normal mode

[matthewmturner]

@seryj FYI adding page up/down and i did try shift+enter but im having trouble with it(the KeyModifier::SHIFT isnt being recognized for some reason). will need to come back to it or table for now.

Perhaps its unsupported by crossterm crossterm-rs/crossterm#400

[matthewmturner]

Alt(Option on mac)+Enter might be an option although that wouldnt align with other tools. What do you think @seryj?

[seryj]

For me, it's an absolutely acceptable solution. I mean, yes, it does not align with other tools... but you know: how many other terminal UI tools for data analysis do exist?! At least out off my head I can call exactly zero. Having such a tool is really a big gain and such small differences really do not play a big role.
At least, I see it this way. And if at some point people really start using this tool extensively, there will be solution for other key bindings.

Man even alt enter is giving me lots of issues. Been digging through other peoples hacks but still not getting the key combination recognized. i think i will just have execution via normal mode for now and come back to this.

[matthewmturner]

well i think i got a baseline interface down to execute with enter from normal mode. not ideal but i think good enough for 0.1. i really want to get alt+enter or something of the sort supported though in the next release.
