Most non Mac laptops have a dedicated "right click" key on the keyboard. If I remember correctly hitting Shift+F10 did the same
Is there something similar for a Mac? I know right click on the trackpad works. Also Command+Click.
I am looking for a shortcut using keyboard only.
Yes. Thats what I also do.
However, I find using the keyboard faster than the mouse/trackpad.
This is one thing which I don't like about the Mac. It does not offer as much support for keyboard shortcuts as much as other OSs. When I was on Ubuntu, I never ever needed to use my mouse. Everything was a keystroke away.
There's a setting under "Universal Access" in the system preferences called "Mouse keys" which I believe does what you want, but it only works on a full keyboard with a numeric keypad, not a laptop. There might be a third-party extension which does this.
But I'm with Bear, can't imagine why you'd want it.
