System-wide terminal accessible via hotkey on macOS

Burton Bradstock, England

When pairing with other developers, I oftentimes notice them spending more time than necessary on things that are neither interesting nor should take a lot of time.

One of these things is opening a terminal window so commands can be entered.

Very often I have observed developers move around windows on the screen in search for a previously opened terminal. While it is possible on macOS to switch between applications using + tab or shift + + tab, there are certainly faster and better ways of reaching a terminal. While it is also possible to open an internal terminal window in any JetBrains IDE using + F12, these windows are usually too small to show a lot of information, and at the same time they take away space that is better suited for displaying code.

TotalTerminal provided a system-wide terminal available on a hot-key - until OS X El Capitan was released in September 2015. Because of a lack of compatibility out of the box and a lack of interest by the original maintainers, development was stopped. Instead, the maintainers suggested to switch to iTerm2, which offers similar functionality.

If iTerm’s documentation for hotkeys doesn’t suffice, here’s a step-by-step guide for setting up a full-screen, system-wide terminal accessible via hotkey:

Basic Setup

Download iTerm2, move iTerm.app from Downloads to Applications, and open iTerm.

In iTerm, press + , to open preferences.

iTerm preferences

Go the Keys tab, and click on the Create a Dedicated Hotkey Window… button in the lower left.

Go to Keys tab

In the panel that opens up, check the Double-tab key checkbox, and press OK.

Check the Double-tab Key checkbox

Congratulations, your hotkey window has now been configured and can be toggled on and off by double-pressing the Control key!

In action with default settings

Customization

In order to open terminal windows or tabs using the previously used location, go to the Profiles tab, select the Hotkey Window profile, select the General tab, and in the Working Directory section, click on Reuse previous session’s directory.

Click on Reuse previous session's directory

In order to change the font, go to the Profiles tab, select the Hotkey Window profile, select the Text tab, and and in the Font section, click on Change Font to select your favorite font. Personally, I use Operator Mono by Hoefler & Co..

Click on Change Font

In order to reduce distraction and increase the size of the hotkey window, go to the Profiles tab, select the Hotkey Window profile, select the Windows tab, and in the Window Appearance section, reduce Transparency to opaque, then in the Settings for New Windows section, click on the Style options, and select Fullscreen.

Reduce transparency and set style to fullscreen

Congratulations, your hotkey window is now full-screen!

Hope it helps!
