Thread: Javascript shortcut and global shortcuts
Started 3 weeks, 6 days ago by macveera
I want to configure ctrl+shift+z as a shortcut for an action in my page. But the key combination is already a global shortcut for my music player. Can i override the global shortcut or prevent the global shortcut action or just intimate the user that a global shortcut already exists for the key combination

No way. Javascript is able to capture the keystrokes, but if the keystroke (or the combination of keystrokes) are allocated, by default, to the Operating System operations, javascript can not change their behaviour. Javascript is client-side language, it can not "touch" the OS. But probably you may alert the user about the fact that combination already does something else.

Create an alert('Sorry, we cannot offer you the functionality of using CTRL or SHIFT keys in this application. Reason being, JavaScript cannot access those keys due to the nature of this language and your Operating System. For all we know, you don't even <em>have</em> those keys.').
