Adjustable Keybinds!!!

[Doublecoin]

I'm not sure if this has been suggested all to hell, but I would really like to see this implemented. Those of us detestable cretins who use Chromebook OS, mainly the itty-bitty school-children who can't afford to get an actual home laptop, and others who just like to use Chromebooks for whatever reason, have a bit of issue with certain things. Mainly the alt keys, alt+- minimizes the tab, alt++ resizes the tab, and thus it makes it annoying to try to change a specific note's volume. Of course, the mouse wheel option exists, but sometimes it gets a bit aggravating when you keep going over or under the wanted volume. So, I suggest an option to change keybinds, allowing for more accessibility across all platforms. 

Thanks for reading, now pls consider it, for if you do, I will love you forever!
