• Works in Sublime Text/IntelliJ Idea/Chrome/Slack
• Expands snippets without preceding space i.e. 30eur to 30€
  • If snippet needs preceding space or start of line - use regexp \b i.e. s/\bv$/✔/g; converts v to ✔ only if its separate symbol
• Expands snippets with symbols i.e. -> to →
• Expands commands i.e. now to formatted todays date, mon to to formatted next mondays date
• Stores all snippets in one file
• Works with Ubuntu 16.04

• If command supports tunneling, display it in title
  • I.e. ssh -L 80:localhost:80 server_nickname will set title user@[80]server_nickname
  • Avoid accidental closing of such tabs
• Appends some useful aliases to existing ~/.bashrc
• Preserves command history on multiple sessions

See sssh
