Add Ctrl + arrow keys to control menu

[Kurtsley]

Need to add an entry for the Ctrl + arrow keys to fast pan the map. Would like input on the exact wording. I was thinking either:

CTRL + ARROWS Fast scroll the map or HOLD CTRL Fast scroll the map

For some reason scroll sounds better than pan even though it doesn't make as much sense. Thoughts?

I think of those options CTRL + ARROWS is better. Not sure about scroll vs pan, though. Might ask around and gather some opinions.

Hi! I'd like to contribute to the repo. Is this issue a good place to start?

[Kurtsley]

Go ahead, overlay_display.py is the file to you want to look at.

[mushahidq]

Thanks! Does this look good?

[ChrisNeedham24]

Looks great! We'll still need to standardise between pan and scroll, though, so at least one more change will be needed.

[Kurtsley]

I know of at least one more key that will needed to be added to this menu, the M key. Since it is getting crowded, either the Ctrl + arrows should be fit into one line or the menu could be extended vertically. Maybe need a separate issue for this.

[ChrisNeedham24]

That's a good point, @Kurtsley. I think then maybe a better idea for this one would be to fit it onto one line, and then move the descriptions a little to the right. I've also talked with a few people about pan vs scroll, and we generally agreed that pan is a better descriptor because scrolling seems to suggest up and down only.

Fast pan does sound a bit odd, though, so how about Quickly pan the map, @mushahidq?

How does this look?

[ChrisNeedham24]

Looking great! Perhaps the text could all be moved over slightly so that the empty space is equal on each side, though?

Looks good to me, @mushahidq!

There may be some minor merge conflicts for this now due to #89. Hopefully nothing too major.
