Add Keyboard shortcut for clearing check boxes

[KiwiCNC]

It would be advantageous to add a keyboard shortcut for clearing the check boxes by column so that if using an interactive foot switch to check the boxes the you could do a long press at the end of you build to clear the boxes ready for the next board assembly. This would remove unnecessary movement to grab a mouse, select the column and then double click. then move back and prepare to place more parts, improving cycle time and manufacturing processes. Maybe a simple 'S' for sourced or 'P' for Placed, ect to clear the column.

Great use case for manufacturing workflow optimization. I'd suggest implementing column-scoped keyboard shortcuts by mapping keys to column indices—for example, Ctrl+Shift+1 through 9 to toggle all checkboxes in columns 1–9. This avoids conflicts with single-key shortcuts and maps intuitively to physical keyboard layout. The implementation would hook into the existing checkbox change handlers and traverse the column DOM to update all checked states atomically. A global "clear all" shortcut (e.g., Ctrl+Shift+0 or Escape) would also be valuable as a faster alternative to clearing individual columns. This would eliminate the context-switch overhead you mentioned and keep focus on assembly placement.
