crossair shortcut not working and we can't change the input

The crossair shortcut is not working (software) and besides we can't change the input

very used shortcut, it would be nice to have a shortcut

now a suggestion: I would also like to have a shortcut to show/hide the trading map, we always need a clean chart (but I like the map) so I just want to switch quickly (maybe show/hide all the figures? it would be really cool)
