+Typing goes to selected panes whenever multiple panes are selected. With zero or one pane selected, input goes to the focused pane. When the one-line command bar is focused, typing stays in that bar; Enter runs the command from the cwd shown in the prompt and keeps output hidden until expanded.
 
 Renamed pane headers replace the numeric prefix for the current session. Saving a blank name restores the default number.

+# Dedicated command bar
+
+Date: 2026-07-07
+Release target: unreleased
+
+## Summary
+
+- Added a dedicated one-line command bar above the GridBash status footer.
+
+## What Changed
+
+- The live view now reserves a command prompt line that starts in the directory where GridBash was launched.
+- Alt-arrow focus navigation can move into and out of the command line alongside panes.
+- Commands run through the host shell with output captured into a hidden buffer by default.
+- `Alt+e` toggles the captured command output panel, leaving `Alt+x` for pane swapping.
+- Built-in `cd`, `pwd`, `clear`, and `cls` behavior keeps the command cwd useful without requiring a persistent shell.
+- The command line was ported onto the current grid behavior without regressing pane sleep, swap, mouse wake, usage labels, runtime resize, or worktree labels.
+
+## Why It Matters
+
+- Users can run quick workspace commands without stealing input from a live agent pane or dedicating a full pane to command output.
+
+## Validation
+
+- `npm test`
+
+## Release Notes
+
+- Adds a focused command bar with hidden output capture and Alt-key output expansion.
