SciTE, Word, IExplorer, FireFox, Opera browser – these popular user-friendly applications provide a valuable feature – when you hold Ctrl and scroll the mousewheel the window contents is scaled by changing on-screen font size.
EmEditor can be enhanced in a similar way and this is really great – now I use AutoHotKey script to make this possible:
#ifWinActive ahk_class EmEditorMainFrame3
^WheelUp::postmessage,0x111,0x11115,0
^WheelDown::postmessage,0x111,0x11116,0
#ifWinActive
that’s all :-)
