# Lizzie Siegle - ZSH Tricks to Blow Your Mind (Highlights)  ## Highlights - 1. My teammate Valériane Venance tweeted about the take command which creates a new directory and changes to it It's a oh-my-zsh function - 5. Perform calculations from the command line like a calculator. zcalc * The result of the calculation on the line preceded by ` 4> ` is available as `$4`. * The constants PI (3.14159...) and E (2.71828...) are provided. * The variables ans (the last answer) and stack (the stack in RPN mode) may be referred to directly; stack is an array but elements of it are numeric. - 7. Park a command. Ctrl-q "parks" the command you're currently typing and takes you back to the prompt, letting you start over and type another command. * `Alt-?` - Show which command * `Alt-h` - Show man page of current command
