Adds Keyboard shortcuts

[GrantComm]

Adds Shortcuts for navigating tabs and searching events and command buffers. There is also a menu item under 'Help' that lists out the new shortcuts.

I'm getting build errors with this PR:

Could be something wrong with my build. I'll look into it.

Also, I just enabled the GitHub checks. Let's see if GitHub Actions also reports a build error...

Ok nevermind, it was an issue with my cmake. I solved it and am able to build now.

However, there are some weird Windows build errors as well as lint issues. If you don't have access to a Windows build machine and need help, let me know and I can try building it on my windows machine at home.

Yeah, I see it is failing the windows build. I don't have a windows machine, so when you have the time could you try running on yours?

Looks like your recent commits fixed the Windows issue. I also verified that it builds on my Windows machine.
