Function parseKeystroke

Parse a keystroke into its constituent components.

Returns

The parsed components of the keystroke.

Notes

The keystroke should be of the form: [<modifier 1> [<modifier 2> [<modifier N> ]]]<primary key>

The supported modifiers are: Accel, Alt, Cmd, Ctrl, and Shift. The Accel modifier is translated to Cmd on Mac and Ctrl on all other platforms.

The parsing is tolerant and will not throw exceptions. Notably:

• Duplicate modifiers are ignored.
• Extra primary keys are ignored.
• The order of modifiers and primary key is irrelevant.
• The keystroke parts should be separated by whitespace.
• The keystroke is case sensitive.
