Edit the inf file to include the path to your MMEditPlus.exe
Place the dll an dinf files into a folder named nppMM inside the plugins folder.
It is difficult to edit the inf file once it's placed in the Program Files folders

Exe Path = C:\Program Files (x86)\CCom\MMedit\MMEditPlus.exe
VR Shortcut = alt 121
Format Shortcut = alt 122
Indent = 1
Tab size = 2

For the two shortcuts, alt, ctrl or shft do as expected.
The number represents the ascii value of the key eg 65 for "A'
Function keys start at 112 for F1

Indent of 1 causes all normal lines to start 1 tab=stop in.
FUNCTION etc strat full left.

Tab stop sets the number of spaces used for an indent.
