The frontend exposes keybinding types and a JSON-editable array configuration. Keyboard handlers now resolve configured commands, including chords and platform-specific AI bindings.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Return false when commandStr does not name a direction.
block:split-chord returns true for any commandStr. If a user configures an unknown value, the handler performs no split, reports the key as handled, and blocks fallthrough to the focused block. The other argument-driven handlers (tab:switch-num, block:focus, block:focus-num) reject invalid arguments with false. Align this handler with that contract.
🐛 Proposed fix
"block:split-chord": (commandStr) => () => {
const direction = commandStr;
if (direction === "up") {
handleSplitVertical("before");
} else if (direction === "down") {
handleSplitVertical("after");
} else if (direction === "left") {
handleSplitHorizontal("before");
} else if (direction === "right") {
handleSplitHorizontal("after");
+ } else {
+ return false;
}
return true;

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.

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.
