I was wondering if anyone has figured out a way to enable the press-and-hold accent popup in Terminal.app, where it does not work out of the box? Does not have to be press-and-hold, but some way to bring up the popup.
I'm used to the unix-style Compose key, but the accent popup seems like a good substitute, especially given that it should also be possible to configure it to support Greek alphabet (for maths), following the instructions in another question: How to add characters to the press and hold character picker in OS X Lion? . But if it won't work in Terminal.app as well, then I'll have to set up a Compose key as explained here: http://lolengine.net/blog/2012/06/17/compose-key-on-os-x .
