Use case or problem
Depending on my view, I frequently want to change the font size, but the existing solution (ctrl+=) zooms the entire interface. There is no solution to bind a keyboard shortcut to zoom the font, but a slider in the settings exists, so it is possible.
Proposed solution
Simply add the keyboard shortcuts/hotkeys Increase font size, and Decrease font size.
