Once the MacOS Terminal app has been opened, a menu bar will appear exactly in the upper left corner of the screen. This menu contains some preferences that could improve the user experience and use of the Terminal.
The menu is divided into 6 sections that I will describe briefly to give you a basic knowledge that could be very useful once you have become familiar with the program.


Open from Finder
  • Secure Keyboard Entry: Inside the Terminal section you will find the item “secure Keyboard Entry”, this tool allows the user to enable an additional system security.
    Essentially, this option prevents other Application from seeing what you are typing on the shell.
    It also prevents processes that are working in background from monitoring your keystrokes.
    In a first moment it seems that it doesn’t do anything, that’s because for people who works on their own personal computer, this additional secure may become an unnecessary precaution.
    However, this option could be very useful if you using an unknown computer or a public computer.
  • Hide terminal: Although Shell’s window does not take a lot of space, it is possible to hide the window by pressing ⌘ + H.
  • Hide Others: In the other hand, it’s possible to hide all the others windows (except the Terminal) by pressing ⌥ + ⌘ + H.
  • Quit Terminal: Once you have finished working with the Terminal, you can definitely close it by pressing ⌘ + Q.


Open from Finder
  • New Window: It creates a new window.
  • New Tab: It creates a new tab
  • Close window: This option closes the window without quitting the terminal.
  • Show Inspector: This option allows the user to customise the layout of the shell. This option contains some profiles that you can use instead of spending time to create your own one.
    This option is not permanent, once the terminal has been quitted, the shell is set with the default settings.
  • Edit Title: This options shows the inspector too, but it selects the current title that you want to change
  • Edit Background Colour: This options shows some useful tools to customise the background of the shell.

Open from Finder
  • Undo: Undo the last input action.
  • Redo: Redo the last undone input action.
  • Cut: Traditionally, the cut command was designed to move texts within applications, but, according to the Mac user community, it’s not very intuitive.
    There is a much easier alternative way, the copy and paste, known as ⌘ + C (copy) and ⌘ + V (paste).
  • Copy: Copy the selected text.
  • Copy Special: It copy a selected text by giving you more options. For example, if you have a black background, copy special allows you to copy a selected file without considering the colour of the background
  • Paste: Past the text from the system clipboard.
  • Paste Escaped Text: If you want to copy a text with special symbols, precisely code text, you have to use paste escaped text to maintain the text intact and not have characters interpreted as code.
  • Select All: It selects all the content of the shell.
  • Select Between Marks: It selects a portion of the text between marks.
  • Clear to Previous Mark: Delete the last command and its contents.
  • Clear to Start: Delete all the content up to the start.
