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.

…pan-zoom # Conflicts: # src/client/InputHandler.ts
🤖 Claude Code ReviewVerdict: The phantom- Findings: 0 high · 0 medium · 1 low File: [Low] On macOS, a zoom key released while Cmd is held now stays stuck after Cmd is released OpenFrontIO/src/client/InputHandler.ts Lines 923 to 956 in 2c63d5a The comment kept above this block says the reason it exists: while Cmd is held, the browser swallows the keyup of any other key. The new logic undoes that protection in two ways:
Your new tests ("a held KeyE continues to emit zoom after Control or Meta is released") need the key to keep working while it is really still held. The cleanup cannot tell that apart from a keyup that was swallowed, but it does not have to guess. Track which zoom keys got a keydown (or a repeat) while the modifier was down. When the last modifier is released, keep a key only if it was held before the modifier and is not a Meta case. Simplest version: apply the "held before" exemption only to Control, and for Checked for bugs and CLAUDE.md compliance. |
…d keys on Control release
🤖 Claude Code ReviewReviewed range: Verdict: The Cmd/Ctrl regression from the last review is fixed. Releasing Meta clears every zoom key again, and only Control keeps the keys that were held before it. One low-severity gap is left: the new cleanup does not handle Shift-modified zoom binds, which are what this PR enables.
