i have gedit 2.30.2 installed (Latest build) and Mac OSX 10.6.5 . I cannot get it to write a curly bracket with + + "8" . On Ubuntu, no problem, on XCode no problem, but gedit won't let me write a curly bracket... I searched on google a lot and found everytime the same answer: use + + "8" .... PLEASE HELP
Quite late, I know, but I think, what you want is actually this.
right-click on text window of gedit, scroll down to "Input Method" in the contextual menu, and select "Multipress". You probably have "Simple" selected, as that is the default.
I was mad with disbelief when I could not type #.
