Using the command palette
Open the command palette with cmd + shift + p (OSX) or ctrl + shift + p (Linux/Windows) and type “split”. You’ll see options for Up, Down, Left, and Right split.
Using keyboard shortcuts
Split the current tab in a direction with the following shortcuts
- Up cmd / ctrl + k then ↑
- Down cmd / ctrl + k then ↓
- Left cmd / ctrl + k then ←
- Right cmd / ctrl + k then →
You can close an active split pane with cmd / ctrl + k then cmd / ctrl + w.
Move between panes
If you want to move between open panes (with the keyboard) you have to modify your keymap file. Go to Atom -> Open Your Keymap and include this:
'body':
'cmd-alt left': 'window:focus-pane-on-left'
'cmd-alt right': 'window:focus-pane-on-right'
'cmd-alt up': 'window:focus-pane-above'
'cmd-alt down': 'window:focus-pane-below'
'cmd-alt-2': 'pane:split-right'
'cmd-alt-3': 'pane:split-down'
This is my personal setup. I was used to Sublime’s default cmd + alt + arrow. Change the left side commands to your personal preference.
Note
You need to press cmd-alt once, release, and then press the arrow button. Otherwise it won’t work.
