+## close-all-windows-but-current
+
+```
+close-all-windows-but-current
+```
+
+On the focused workspace, closes all windows but current. This command doesn't have any arguments.
+
 ## exec-and-forget
 
+```
+exec-and-forget bash_command
+```
+
+Runs `/bin/bash -c '$bash_command'`. Stdout, stderr and exit code are ignored.
+
+For example, you can use this command to launch applications: `exec-and-forget open -n /System/Applications/Utilities/Terminal.app`
+
 ## exec-and-wait
 
+```
+exec-and-wait bash_command
+```
+
+Runs `/bin/bash -c '$bash_command'`, and waits until the command is terminated. Stdout, stderr and exit code are ignored.
+
+Please prefer `exec-and-forget`, unless you need to wait for the termination.
+
+You might want to wait for the termination if you have a list of commands, and you want `bash_command` to exit until you run the
+next command.
+
+Suppose that you have this binding in your config:
+```toml
+alt-enter = ['exec-and-wait open -n /System/Applications/Utilities/Terminal.app && sleep 1', 'layout floating']
+```
+
+It will open up Terminal.app and make it float. `sleep 1` is still required because `open` returns before the window appears.
+
+## flatten-workspace-tree
+
+```
+flatten-workspace-tree
+```
+
+Flattens [the tree](./guide.md#tree) of currently focused workspace. This command doesn't have any arguments.
+
+The command is useful when you messed up with your layout, and it's easier to "reset" it and start again.
+
+## focus
+
+```
+focus (left|down|up|right)
+```
+
+Sets focus to the nearest window in [the tree](./guide.md#tree) in the given direction.
+
+[Contrary to i3](https://i3wm.org/docs/userguide.html#_focusing_moving_containers), `focus` command doesn't have a separate
+argument to focus floating windows. From `focus` command perspective, floating windows are part of [the tree](./guide.md#tree).
+The floating window parent is determined as the smallest tiling container that contains the center of the floating window.
+
+This technique eliminates the need for an additional binding for floating windows.
+
+`focus child|parent` [isn't yet supported](https://github.com/nikitabobko/AeroSpace/issues/5) because of a low priority.
+
 ## layout
 
-> `layout (h_list|v_list|h_accordion|v_accordion|tiling|floating|sticky...)`
+```
+layout (h_list|v_list|h_accordion|v_accordion|list|accordion|horizontal|vertical|tiling|floating)...
+```
 
-## move-through
+Changes layout of the focused window to the given layout.
+
+If several arguments are supplied then the first layout that describes the currently active is found. The layout specified after
+the found one will be applied. If the currently active layout is not in the list, the first layout in the list will be activated.
+
+`layout tiling` is the only command that makes the focused floating window tiled.
 
 ## mode
 
-> SYNO
+```
+mode name_of_the_target_mode
+```
+
+## move-container-to-workspace
+
+## move-in
+
+## move-through
+
+```
+move-through (left|down|up|right)
+```
+
+This command is an analog of [i3's move command](https://i3wm.org/docs/userguide.html#move_direction)
