Radio Insertion Point Madness

[ArtLaws]

Is there any way to map the keyboard  to make the insertion point go back where its supposed to be.   With out grabbing the mouse and clicking on it.  I cant even figure out which key makes it disappear.  I know the (TAB) Key moves it from channel to channel.

Hotkeys for the different radio channels are /, Shift+/, Ctrl+/ and Alt+/. You can then enter the channel in each of these (for instance 1 (open, Grey), 2 in second (friendlies, green), 3 in third (local friendlies, Purple) and 4 (squad, red)

If you hit the key by mistake and want it to disappear press enter when no text is typed.

To enlarge the text buffer you can use the key above Tab (~ I think on english keyboard)

As far as I know the Tab is used for padlock, and not changing channels.
