WalkthroughThe change adds default and user keybindings to full configuration loading. The frontend exposes keybinding types and a JSON-editable array configuration. Keyboard handlers now resolve configured commands, including chords and platform-specific AI bindings. Global key registrations rebuild after configuration updates and full configuration initialization. Tests cover key generation, merging, disabling, parsing, and missing files. Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This PR adds user-configurable keybindings, but malformed configuration shapes can silently revert users to defaults and configuration updates during a key chord can crash the next keypress; malformed chord definitions can also behave unexpectedly. These bounded correctness and runtime issues should be addressed or explicitly accepted before merging. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Replace hardcoded keyboard shortcuts in keymodel.ts with a data-driven system. Default bindings are defined in defaultconfig/keybindings.json and users can override them in ~/.config/waveterm/keybindings.json. The merge logic preserves defaults while letting users remap or disable individual commands. A "Keybindings" section is added to the Wave Config UI for in-app editing. Changes are picked up automatically via the file watcher.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Reject malformed chord key strings instead of registering a partial binding.
keyStr.split(" ", 2) truncates; it does not group the remainder. Two inputs produce a broken binding:
"Cmd:d Cmd:right"(double space) yields["Cmd:d", ""]. The second key never matches, andCmd:dbecomes a chord prefix that consumes the next key and does nothing."Cmd:d Cmd:e Cmd:f"yields["Cmd:d", "Cmd:e"]. The third part is dropped and the binding fires on a shorter sequence than the user wrote.
Skip the binding when the split does not produce exactly two non-empty parts.

Reset the active chord before rebuilding the key maps. If a configuration event arrives during a chord, clearing globalChordMap leaves activeChord set. The next keydown passes undefined to checkKeyMap, which throws on .keys(). Add resetChord() before clearing the maps.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
Validation still accepts an object for an array file, and the error text does not match the allowed shape.
Two gaps remain in this check:
- A plain object passes for
keybindings.json. The Go loader unmarshals that file into[]KeybindingConfigTypeand fails, so the user only sees the problem later as a config error. - The message on Line 373 always states that the value must be an object. For
keybindings.jsonan array is the required shape, so the text is wrong for a primitive ornullinput.
Select the required shape from selectedFile.isArray in both the check and the message.

Global keybindings are no longer hard-coded in
keymodel.ts. Defaults live inpkg/wconfig/defaultconfig/keybindings.jsonand users can override them in~/.config/waveterm/keybindings.json:keysarrayMerging is done on the Go side and delivered to the frontend via wshrpc; changes
are picked up through the existing config event system.
Testing
pkg/wconfig/keybindings_test.go: 10 unit tests covering merge logic(override, add, disable, no mutation of defaults) and user file parsing
(valid/invalid/missing JSON) - all passing.
