We all can learn something new

Did you can add vertices??? I didnt.

The hotkey is CTRL+LMB (left mouse button)

Thought it was neat just wanted to share.

I heard of the shortcut before but forgot, before I extruded to add verticies on a line.

I like this thread better:
https://blenderartists.org/forum/viewtopic.php?t=16122

took me too long to find that again

i just got the blender bundle so im discovering new hotkeys.
