Shortcut Editor: Add 'Find' and 'Save' keyboard shortcuts

[sonic2kk]

Overview

When using the Shortcut Editor (which is my new favourite thing 😄) I instinctively pressed "Ctrl+F" to focus the search bar. I figured it would be a useful bit of functionality, so I decided to add it!

While adding it, I also thought a save shortcut would be handy, so I added that too.

There is some precedent for keyboard shortcuts in ProtonUp-Qt, as we already have some on the Main Menu, so I think it's okay to add them to the Shortcut Editor too 🙂

Implementation

These shortcuts are bound using QKeySequence.Find and QKeySequence.Save, which are Qt's built-in per-platform "constants" (I guess?) for these actions. Since we're only targetting Linux with ProtonUp-Qt, it isn't a huge deal, but I think it's nicer to be explicit with a shortcut key combination called "Save" rather than the very, very slightly more ambiguous "Ctrl+S". This is also what we already use for the keyboard shortcuts on the Main Menu.

To wire up the shortcuts:

• The "Find" shortcut has a lambda attached to it that just sets the focus to the searchBox widget.
• The "Save" shortcut just connects to the existing btn_save_clicked method.

If this change is desired, there is room for other shortcuts too, such as Ctrl+N for creating a new shortcut row. Open to all discussion 😄

Future Work

We could probably document these shortcuts on the brand-new wiki to give a bit more visibility on this change. We could have a page for keyboard shortcuts, with a per-screen table of available shortcuts. I'd be happy to take a stab at the markup and attach it to a discussion as I can't directly edit the wiki.

Good suggestion.

Here you go, I've already created a discussion: #358

I think you would need to clone the Wiki and somehow create a PR. I've never tried that before though.
