You can bind keys to the functions "inset-begin" (positions the cursor 
before the first character in the inset) and "inset-end" (positions 
the cursor after the last character in the inset). In both cases, the 
cursor remains within the inset.


To exit the inset, you can use "command-sequence inset-end; 
char-forward;".

But there's a catch with using inset-end or inset-begin like this to 
move out of the inset. If the cursor is at the end of the inset already 
then "command-sequence inset-end; char-forward;" will take you to the 
end of an enclosing inset if there is one, or to the end of your 
document if there is not, which can be disconcerting if all you want to 
do is position the cursor immediately after the inset.


command-sequence line-begin; inset-end; char-right;

takes care of the case when the cursor is already at the end of the 
inset (but still produces the big jump to the end of the document if the 
inset is empty).

Very helpful, thank you!

Huh, weird. I just checked this out on my Linux laptop and selecting the Emacs 
keybindings (Tools → Preferences → Shortcuts → Bind file) gives me the 
Ctrl-a/Ctrl-e behavior noted inside an ERT frame.

Ah, you know what? Ctrl and Cmd are all turned around for me on the Mac. Try 
using Cmd-a and Cmd-e instead! (I had to go into the Shortcuts and explicitly 
assign the functions in question to Ctrl- characters instead of Cmd- 
to get Emacs bindings to work correctly.) I suspect there was a more global way 
to do this in one fell swoop, but I couldn't figure out any other way to do it; 
and it works. ¯\_(ツ)_/¯ But if all you want is some keystroke to get the cursor 
movement you want, you can just use the Cmd- bindings noted.

Thanks for the reply!  Unfortunately, no luck.

I have been using the mac keybindings, plus some customizations.  
Unfortunately, neither with the mac keybindings nor when I change to the emacs 
keybindings (I was hoping to get the code that way) do I see these actions.  
With the mac keybindings, ctrl-e takes me to the end of the on-screen line, but 
not the end of the frame.  Ctrl-a alone seems to do nothing except display "^a 
options" on the status bar at the bottom.  With the emacs keybindings, both 
ctrl-a and ctrl-e yield "unknown function".


Ctrl-o closes the frame and places the cursor to its immediate left; that 
behavior is definitely due to my choice of Emacs keybindings.

Re: shortcut for going to edge of ERT frame?

[Chris Menzel]

For me, Ctrl-a and Ctrl-e move the cursor in an ERT frame to the first and
last characters of the frame, respectively. However, I'm not sure if this
is because I'm using Emacs keybindings or because I'm using a Mac, which
also uses those keybindings in text areas. Ctrl-o closes the frame and
places the cursor to its immediate left; that behavior is definitely due to
my choice of Emacs keybindings.

shortcut for going to edge of ERT frame?

[David Pesetsky]

Is there any way to program a key so that if you are typing within an ERT 
frame, it takes the cursor to the last (or first) character in that frame?  

Also useful would be a way to exit the frame — landing at at the first non-ERT 
character to the left or right of the frame.
