I have a lot of user defined live templates, but I don't use them quite often enough that I always remember what they are.
Is there a shortcut or hotkey to bring up a quick list without opening up settings and digging through the ones I've defined?
Invoke Code | Insert Live Template
(Ctrl + J) to bring the list of all applicable in current context live templates (or just use code completion popup if they are listed there)
Select desired live template
Invoke View | Quick Documentation
via shortcut (Ctrl + Q)
Now you should see both: list of live template + template body.
