Configuring keys as standalone

[amihsekai]

I’m using a custom keyboard layout and have moved some keys (e.g., ?, !, etc.) from their Shift-modified positions to the normal layout. However, they still act as aliases for Shift-modified versions of other keys (e.g., "?" is an alias to "S-/").

How can I make these keys be considered as standalone by Helix?

Thanks in advance.
