[MENU] Another action on Enter than timeout

[sebastian]

I have this menu:

Code:

#!ipxe
:start
clear scancount
clear completeinput
set deftimeout 0
:continue
menu PLEASE SWIPE YOUR ACCESS CARD IN THE CARD READER
item cancel
item --key 0 0
item --key 1 1
item --key 2 2
item --key 3 3
item --key 4 4
item --key 5 5
item --key 6 6
item --key 7 7
item --key 8 8
item --key 9 9
choose --default cancel --timeout ${deftimeout} input && goto process || goto start
:process
iseq ${input} cancel && goto cancel || goto cproc
:cproc
set deftimeout 56
set scancount ${scancount}X
set completeinput ${completeinput}${input}
iseq ${scancount} XXXXXXXXXXX && goto start || goto continue
:cancel
iseq ${scancount} XXXXXXXXXX && goto step2 || goto start
:step2
chain http://www.myserver.com/cardlogin.cgi?accesscard=${completeinput}

currently, it works pretty well. But I want to assign Another action if the user press ENTER, than if the timeout expires.
So if the user press ENTER, I want something different happen, than if the user Waits until timeout (56 milliseconds) expires.

All menu items have shortcuts so it does not matter if the user is unable to use the Arrow keys and select a item and press enter.

I tried with assigning --key 0x0a but didnt work.
(KEY_ENTER -> LF -> CTRL_J -> 0x0a)
(eg "item --key 0x0a done")

Is this possible to tie ENTER permanently to a menu item?
