Option to invert numbers and symbols on the number row

[jeandeaual]

It would be nice to have an option to invert numbers and symbols on the number row, like on the French layout, Spanish layout, some QWERTZ layouts or the Programmer Dvorak layout.

This would mostly be useful for programmers, people using a Compose key to input special characters or to add hardware support for Programmer Dvorak.

I think this means inverting the shift modifier when a number row key is pressed. The main issue is with the behavior of the Caps Lock key:

• With Programmer Dvorak, Caps Lock works for the number row (e.g. pressing Caps Lock then [ outputs 7. This is useful when you want to input multiple numbers in a row.
• With the French layout, Caps Lock works for the number row AND special character keys not in the number row such as $, *, !, etc.

I'm not sure which approach would be the best here.

What do you think about this possible feature?

Adding European keyboard layouts has been a low priority since we do not export NISSE to Europe directly. To support the standard 102 keyboard layout, the firmware needs to support another mode that can generate KEY_NON_US_BACKSLASH scan code. The required change would be very small anyway. Device drivers should be able to handle generic features in each country beyond this.
