Is there a way I can map verts / edges / faces to my 1 2 and 3 keyboard buttons like Modo? Having to go through a pie menu to select different component modes really slows me down a lot. Can't seem to find them under the user preference/input menu. Thanks!
You can use Ctrl+Tab and select Vertex, Edge or Face from the popup menu, which will appear under the mouse. As far as I know, this is the fastest way to switch.
Update for 2.8: This function is now available by default when pressing 1, 2 and 3. To remap this back to the original behavior see this question.
