+## Pane type bindings
+
+Keybindings can be specified for different pane types as well. For example, to
+make a binding that only affects the command bar, use the `command` subgroup:
+
+```
+{
+    "command": {
+        "Ctrl-w": "WordLeft"
+    }
+}
+```
+
+The possible pane types are `buffer` (normal buffer), `command` (command bar),
+and `terminal` (terminal pane). The defaults for the command and terminal panes
+are given below:
+
+```
+{
+    "terminal": {
+        "<Ctrl-q><Ctrl-q>": "Exit",
+        "<Ctrl-e><Ctrl-e>": "CommandMode",
