Change iTerm2 Profile How can I change the profile of my current iTerm2 session?

If I click Profiles and select one, it opens a new session instead of changing the current one.
You have to "Edit" the session.

The easiest way to do this is to right click on anywhere on the open iTerm2 window, select Edit Session...  A Preferences pane will appear and under the General tab, look for the Profile Name selection box.   Double click on your desired profile.
