FireMonkey Virtual Keys

Virtual Keys

Virtual keys provide a symbolic representation of keyboard keys pressed by the user. Virtual keys are used in methods like FMX.Forms.TCommonCustomForm.KeyDown.

Virtual key constants define scan codes of keys on PC keyboards. Mac keyboards have different scan codes for some keys. FireMonkey converts Mac scan codes to be equal to the virtual key constants defined in this table.
