Switching to tabs to the right or left of the current tab in Notepad++

keyboard shortcutsnotepadtabs

How can I switch to the document to the left or right of the current document in Notepad++?

For example, if I have documents A, B, and C open, and I'm currently editing B, I would like a shortcut to be able to:

  1. switch to document A, like. . . (Alt–LeftArrow or Ctrl–Pageup)

OR

  1. switch to document C, like. . . (Alt–RightArrow or Ctrl–PageDown).

All I've found is a way to switch to next or previous documents based on the "history" of when the document was last opened, for example:

(Ctrl–Tab and Ctrl–Shift–Tab)

The examples I have found are useful, but not what I want.

Is what I am asking for possible?

Update

The functionality is included by default in Notepad++ v6.4.5 and later. 6.4.5 was released August 9th 2013. Note the current version is 7.5.8 released July 23rd 2018.

If you are using a version of Notepad++ older than v6.4.5, the rest of this answer still applies.

Natively

You can do this natively in Notepad++, but in order to replicate the behaviour of Firefox, you need to disable the document switcher and MRU behaviour.

Disable MRU functionality

  1. Navigate to Settings > Preferences... > MISC..
    • Where it says Document Switcher (Ctrl+TAB) uncheck the first check box Enable.
    • Hit the Close button.

Create the Ctrl+PGUP/PGDN shortcuts

  1. Navigate to Settings > Shortcut Mapper....
    • Make sure you are on the Main menu tab.
    • Scroll to the bottom and you should see in entries 192 Switch to previous document and 193 Switch to next document.
    • By default these should be mapped to Ctrl+Shift+Tab and Ctrl+Tab respectively.
    • Double click anywhere on the 192 line and change it to Ctrl+Page up.
    • Double click anywhere on the 193 line and change it to Ctrl+Page down.
    • Hit the Close button.

That's it!

Please note that you will no longer have access to the Ctrl+Tab/Shift+Tab MRU behaviour now. If, like me, you cannot live without this read on.

Another (better) option

Notepad++ defaults to using the back and forward buttons on a mouse to switch to the adjacent left and right tabs, so if you are a fan of AutoHotkey, you can use this little script:

#IfWinActive, ahk_class Notepad++
; Switch to the adjacent tab to the left
^PgUp::
    Send, {XButton1}
    Return
; Switch to the adjacent tab to the right
^PgDn::
    Send, {XButton2}
    Return

This won't interfere with other programs and enables to you have your cake and eat it! You can navigate left and right through adjacent the tabs using Ctrl+PgUp and Ctrl+PgDn and you can still switch to your last used tab using the built-in document switcher functionality using Ctrl+Tab and Ctrl+Shift+Tab - just like Firefox :)
