External Pause/Resume Button & Manual Tool Change

Right now I have an external button for pause/resume (just got it working, awesome) but when it comes to manual tool changes I still have to hit enter on the keyboard. Is there any way to have this work on the same button?
Once I get my cycle start and e-stop buttons wired up I'm going to be out of inputs on my CNC4PC BOB (my spindle and limit/home switches are the last two input pins).

My pause/resume is from this excellent post by BigJohnT: forum.linuxcnc.org/forum/47-hal-examples...tton-using-one-input

It certainly is possible, as that is how my machine works. (it's a touchscreen so hitting "enter" was really quite hard)

There is a HAL pin created by hal_manualtoolchange that has the same effect as hitting enter or clicking the dialog.
The pin is called hal_manualtoolchange.change_button.

then you use a OR logic
you can have many Or in ligic steps
gnipsel.com/linuxcnc/hal/or2.html

named or2 logic is a better reding
loadrt or2 or2.btn-ext-a,or2.btn-ext-b ....
addf or2.btn-ext-a servo-thread
addf or2.btn-ext-b servo-thread

net button-1 or2.btn-ext-a.in0 <= your-pin
net button-2 or2.btn-ext-a.in1 <= your-pin

net pause halui.program.pause <= or2.btn-ext-a.out
