Google Chrome – Shortcut for Accessing Tab Menu

There are two answers here, depending on exactly what your question is:

• If what you want to do is just what your example states, try this:

  • Launch Terminal, and open its preferences ⌘,.
  • In the Settings preference pane, select Pro in the left-hand column.
  • At the very end of the left-hand column, click the Default button.
    
    

  At that point, you'll find that ⌘N now opens a new window in your preferred style, and ⌘T does the same for a new tab.

• If your example was just an example, and it's some other app where you want to add a keyboard shortcut, you should be able to do it via System Preferences → Keyboard → Keyboard Shortcuts → Application Shortcuts → +.

  As @Nano8Blazex said, you can usually just enter the name of a nested shortcut and it will work fine.

A workaround would be: Ctrl + L, + C, + W, + N, + V, and Enter.

Or

F6, Ctrl + C, Ctrl + N, Ctrl + V, Enter and an optional Alt + Tab, Ctrl + W, Alt + Tab, to close the old tab.

You could automate the whole thing with AutoIt (under Windows) and create a Hotkey for it (here, it's Ctrl + Alt + x):

HotKeySet("^!x", "split_tab")
Func split_tab()
    Send("{F6}^c^n")
    Sleep(999)
    Send("^v{Enter}")
    Send("!{Tab}^w!{Tab}")
EndFunc

I always have an additional application like this running in the background, offering useful keyboard shortcuts which automate and simplify tasks.

Alternatively, you can hit Ctrl + L instead of F6, which would be substantially easier as your hand does not have to leave the home row.
