Add mousewheel controls for font size and true zoom
Posted: Sat May 30, 2026 7:09 am
For clarity I've used only "Ctrl" rather than the full Windows/macOS "Ctrl/Cmd" and "Mousewheel" rather than "mouse wheel"
Proposal (minimal dev work):
Ctrl+Shift+Mousewheel adjusts font size (same as `Ctrl+0/9`)
- Mousewheel provides more intuitive control of font size.
- Complements existing use of Mousewheel for H/V scrolling.
Further enhancement (requires new code):
Ctrl+Mousewheel adjusts true zoom
- Enables adjustment of magnification without affecting layout
- Follows the established convention in browsers, Microsoft Office, Adobe apps, etc.
In summary
Currently:
- Mousewheel: Vertical scroll
- Shift+Mousewheel: Horizontal scroll
Proposed additions:
- Ctrl+Mousewheel: True zoom
- Ctrl+Shift+Mousewheel: Font size adjust
These additions would complete the Mousewheel's role in screen navigation.
