   - /monitoring splits screen into three panes: label:UP, label:AL, notlabel:AL,UP
     This is the same as two commands:
      - /split label:UP label:AL notlabel:AL,UP
      - /mode monitoring
   - /run <tag> splits screen into three panes: label:open, label:doing, label:done
     /run AA,BB is the same as two commands:
      - /split tag:AA,BB;label:open tag:AA,BB;label:doing tag:AA,BB;label:done
      - /mode run
   - /set-tatwebui-url <urlOfTatWebUI> sets tatwebui-url in tatcli config file. This
      url is used by Ctrl + o shortcut to open message with a tatwebui instance.
   - /split <criteria> splits screen with one section per criteria delimited by space, ex:
      /split label:labelA label:labelB label:labelC
      /split label:labelA,labelB andtag:tag,tagb
      /split tag:myTag;label:labelA,labelB andtag:tag,tagb;label:labelC
   - /save saves current filters in tatcli config file
   - /toggle-usernames displays or hides username in messages list
