Keyboard and mouse usability improvements in the editor

[lydell]

• Require ctrl to be held while scrolling to zoom. Rationale:

  • Both the sidebar and the canvas area has OS-native scrollbars visible, but OS-native scrolling gestures only worked in the sidebar. Trying to scroll in the canvas area resulted in zooming.
  • This allows scrolling naturally on a touch pad.
  • I’d say you pan much more than you zoom.
  • We have hotkeys for zooming.

• Add + as a hotkey in addition to =. + is the logical opposite to -, but = is used to avoid having to press shift on US keyboards (where shift-= is +). Other keyboard layouts do have + keys and = requires shift instead.

• Make the zoom hotkeys zoom towards the mouse pointer. This makes them much more useful I think.

• Use cmd instead of ctrl on macOS. That feels much more natural.

Extra note: This “workaround” (?) might not be needed anymore: https://github.com/eevee/lexys-labyrinth/blob/430fa5c354c4454dd1954897ed3d4364d8acd3b3/js/editor/main.js#L241-L246. I haven’t investigated yet.
