Underscore character during prog editing

[Giancarlo]

Hello,
in program editing while the alfa annunciator is ON, it is possible to:
- add a comma (DOT) clicking the '.' key.
- and add a '=' clicking on SHIFT and then '=' key.

everything is fine so far.

It is not clear why it is possible to:
- add a space clicking the 'space' key.
- BUT IT IS NOT POSSIBLE ADDING THE UNDERSCORE clicking on SHIFT and then 'SPACE' key.
Clicking on the SHIFT and then 'SPACE' it simply add another space so, if you need to add an UNDERSCORE you have to DESELECT the ALFA (orange ) key and then SHIFT and again 'SPACE' key.

Do you think it is possible to add this functionalitiy in the future?

Thanks

Giancarlo
