Add keybinds for test/submit

**Is your feature request related to a problem? Please describe.**
A user must use a mouse to test or submit their code

**Describe the solution you'd like**
A keybind, similar to LeetCode, that allows for the user to run or submit their code from a keybind.

The LeetCode Keybinds are `Ctrl + '` for test and `Ctrl + Enter` for submit, we could use something like those

No files, tests, or entry points are named. Start by locating the existing test and submit controls and their event handlers, then check how keyboard events are handled elsewhere. Done means the requested keybinds trigger testing and submission without mouse use, with the existing actions still working.
