Is there a simple way to add this kind of options to browser extension(I'm using the crossrider framework to build cross browser extension)?
Users just need to type the shortcut they want and click the save button
This is a screenshoot from the send to kindle
chrome extension
With crossrider API you can add keyboard shortcuts
appAPI.shortcut.add('ALT+CTRL+X', function (event) {
alert('Alt+Ctrl+X');
}, {type: 'keydown'});
Edit:
You can also store the user shortcut preferences on the extension database:
appAPI.db.set('user_shortcuts', ['Alt+Ctrl+X', 'Ctrl+F12']);
