badpunman had nice idea that keyboard shortcuts should be more visible and documented.
Hover tooltips for the buttons that have keyboard shortcuts should show those shortcuts.
Sometimes there might be room to show the keyboard shortcut in the button itself like in “Analyze Game” it could say “Analyze Game (F1)” or something like that. For the smaller buttons like marker tools in analyze mode and other small icon buttons the only way would be to show a hovering tooltip.
“Back to game” could also be “Back to game (ESC)”
