Up/Down Key not working in Onenote 2016 for Autohotkey

I mapped alt+i/k to Up/down key using Autohotkey, with the following code:

!i:: Send {up}
!k:: Send {down}

These remappings work with every application except Onenote 2016. I checked it online and found some discussions in the following links:

https://autohotkey.com/board/topic/15307-up-and-down-hotkeys-not-working-for-onenote-2007/

https://autohotkey.com/board/topic/41454-remap-key-doesnt-work-in-ms-onenote/

They suggest to use sendplay or sendraw, but these didn't work for me. Can anyone help me with this?

It works if you use SendPlay and run AHK script with UI Access

This is your script with Send changed to SendPlay:

!i::SendPlay {up}
!k::SendPlay {down}

It emulates ↑ and ↓ as you expect. Tested with OneNote 2016 on Windows 10.

How to enable SendPlay: (which initially does nothing in Windows 10)

1. Save the above mappings into AHK file. I used file updown.ahk with only these two lines.

2. Right-click the above AHK file and from its context menu, select Run with UI Access (this actually does the trick)

Troubleshooting:

• The item Run with UI Access is missing from context menu of AHK file

  1. Make sure your AutoHotKey is installed using the installer into Program Files directory. AutoHotKey documentation says UIA is only effective if the file is in a trusted location i.e. a Program Files sub-directory.

  2. In installer options, be sure to check the last item as shown below.  
     

  Tip: if your AutoHotKey is already installed, it is sufficient just to re-run the installer (Installer.ahk found in location of AutoHotKey executables) and check the option. (No need to uninstall and install anew.)

• SendPlay still does not work?

  1. See the FAQ topic How do I work around problems caused by User Account Control (UAC) available either online or inside local AHK help file. (They are the same.)

  2. Similar topic also describing limitations is Run with UI Access (available online or in local help).
