…lso be assigned to other actions. Leading to two actions happening for one key. Add them to the default keybinds they already belonged to being hardcoded keys. Now they can be (un)assigned by the user and the settings modal will make sure they aren't assigned to an action twice. Do the same for the hardcoded Minus/NumpadSubtract/Equal/NumpadAdd keys (they do zoom actions).

1438-1450: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick winCache alternate bindings in
buildKeybindTable().
initializePointerAndKeyboardEvents()starts a 1 ms interval for each initialized handler. The interval evaluates eight alternate bindings per callback, not ten. On the default path, each call creates a fresh 41-entry object throughgetDefaultKeybinds(). This can produce about 8,000 temporary objects per second at the requested interval.Cache the eight resolved values in
buildKeybindTable(). Rebuild the cache when keybind settings change. Preserve configured values, default-present unbound values, and fallback keys.♻️ Suggested refactor

Thanks for this. I think it needs to be merged after #5864 though and needs updates to work with the 5864 changes, as noted here https://discord.com/channels/1359946986937258015/1360078040222142564/1558132935498932404 just now |
…inds (openfrontio#5866) - Support Shift-modified continuous movement and zoom keybinds on top of configurable arrow and zoom defaults (openfrontio#5864). - Update active key tracking and interval evaluation to be modifier-aware via shiftHeld. - Ensure unmodified controls do not trigger when Shift is held. - Dynamically stop/start actions when Shift is released/pressed while holding physical keys. - Prevent phantom ShiftLeft in activeKeys when ShiftRight is pressed. - Add comprehensive vitest suite for Shift-modified continuous controls.

This test configures and dispatches only
