Describe the problem

There is variation in the case of the key identifier text in the default keyboard shortcut settings. For example, I see:

• CtrlCmd
• ctrlCmd
• ctrlcmd

In addition to giving the IDE an unprofessional look, I think this inconsistency could cause confusion for the users who will treat the defaults as references for customizations. Even if they are not case sensitive, the user won't know this intuitively and so will wonder which of the cases they should use.

Expected behavior

Key identifiers are written in a consistent, standardized way everywhere they appear in the Arduino IDE UI.
