- Pressing the tab key in the repl does open the completition window and
i'm able to navigate with "up"/"down", but selecting a completition with "enter"/"return" seems to send an "enter" to the repl. With paredit activated this causes havoc since the form most likely isn't completed yet.
The idea here is that the user should not press an extra key to accept the completion (such as enter). So if the pressed key is clealy not part of the symbol being edited (such as space, enter, (, ), etc.) then it fires implicit completion and applies the key afterwards. This might be somewhat strange for the first sight, but it turned out to be very useful.
Still you can have explicit completion by pressing the completion key twice without editing in between (I do it sometimes). Without editing is important here, because otherwise it just updates the completion window which in fact is also very useful. For example when trying to find out the shortest shortcut for a particular symbol.
And of course you can always close the completion window with Esc or C-g or whatever you like.
