is there anyway to add Ctrl + Enter as a way to enter a post in fast reply. if so then it should be done, i use fast reply a lot

Just simply click the Add Reply button after your post is complete.

fast reply is always open for me. I think it is a setting in your CP.

It is, I have it turned on, so Fast reply is always there.

i know about that, i mean Ctrl+enter to send the post instead of clicking add reply

Ah, I see what you're saying. That would be pretty nifty, eh? I don't know if such an option exists. I always click the "add reply" button after I finished typing in the fast reply space.

Perhaps look in the board help files.
