Key remapping for TagEditor or other programs: AutoHotkey for BT keyboards

Faced with the prospect of pressing the Alt+Ctrl+NumPlus combination for the 1000+ times within a TagEditor translation project, I searched for a nifty key remapper. I thought of Ms IntelliType but it does not work with my BT keyboard*.

Here's what I can recommend for this purpose:

• Install AutoHotkey (link) 
• Modify the autohotkey.ahk file (in C:\Users\[User]\Documents)
  adding the
  
  NumpadSub::^!NumpadAdd
  ;Alt+Ctrl+NumPlus
  
  NumpadMult::!Ins
  ;Ctrl+Ins
  
  NumpadDiv::^!Down
  ;Alt+Ctrl+Down
  lines. (^ stands for Control while ! for Alt)
  
• Rerun the Autohotkey program or select Reload this script menu command
• In Tageditor, press the Numerical Pad Minus or Numerical Pad Multiply keys to test if it works.

 
* To answer a reader's question: why don't I use MS IntelliType Pro for the purpose here? Because it is not compatible with my Bluetooth keyboard:

The price of free: Kingston Office spying on you

When you run the otherwise fine Kinston Office on Android, it tries to ring home, to China:


You have little control over what is sent. Granted, you can block its networking with e.g. LBE, but then you need to block LBE in turn, maybe with the in-built Android Privacy feature.  
Quid custodiens ipsos custodes?

The only privacy solution is to switch off the phone. But then, why have it?
