How to Set Key to Switch to Browser for {Microsoft Windows, Mac, Linux}

By Xah Lee. Date: . Last updated: .

This page shows you how to set a singe key to switch to your favorite app, for {Windows, Mac, Linux}. For example, set F8 to switch to browser, or terminal.

There are 2 or 3 apps we use perhaps 80% of time. So, it's nice to set a single F key to switch to them.

What's wrong with 【Ctrl+Tab ↹】?

Ctrl+Tab ↹】 or 【⌘ Cmd+Tab ↹】 are inferior, because:

If you set a single F key to switch to a specific app, it becomes muscle memory.

Here's how for {Mac OS X, Linux, Microsoft Windows}.

Mac OS X

Use QuickSilver. Just install it and use the GUI to set a key to app. See: Mac OS X Keyboard Layout, Keymapping, Keybinding, Tools.


Linux: Add Key to Switch App


For Windows, one solution is AutohotKey.

You'll need to intall AutoHotkey. See: AutoHotkey Tutorial ⌨.

Here's a sampe AHK script:

; 2010-04-01, 2011-11-27
; launch or switch to firefox

SetTitleMatchMode, 2

If WinExist("Mozilla Firefox")
  If WinActive("Mozilla Firefox") {
    WinActivateBottom, Mozilla Firefox
      } Else {
  Run "C:\Program Files (x86)\Mozilla Firefox\firefox.exe"


Save it as a file and name it launch_or_switch_firefox.ahk, then you can use Microsoft IntelliType (bundled with Microsoft Keyboards) to set F9 to run this script.

Or, in your main AutoHotkey script, add this line:

$F9::Run "C:\Users\mary\ahk_scripts\launch_or_switch_firefox.ahk"
