Choose a different tool.
Well, I guess it the only way. Thanks Jim. I like your videos alot, they help me learning the damn difficult software.
EIDT: I just know, when typing, if I want to quit the text mode, I should press "Esc", then I will press shortcut of different tool, its the fastest way.
Or I can click on the canvas, just one click, so text mode enclosed, then I press shortcut of different tool.
You're very welcome and thank you.
