I thought there was a way to keep the “Special Characters” dialog open for insterting more than one character at a time. This one:
I can’t spot it anywhere, though, and picking out characters, one at a time, re-opening the dialog, etc., is a real pain.
Have I just misremembered? Is there a way to keep this dialog open to choose a second, third, etc., character for insertion, then close the dialog manually? I hope so!
(I’m using LibO 22.214.171.124 under Ubuntu 14.04, FWIW.)
