v0.10+ NotebookActions

NotebookActions is a feature which is very similar to LiveTemplates but allows to use/customize a menu of arbitrary actions.

Items are even simpler:

<|"Label" -> _String,        "ShortKey" -> _String (*char*), "Action" :> _|>
(*e.g.*)
<|"Label" -> "Print date",   "ShortKey" -> "p",              "Action" :> Print @ Now|>

See more in the Readme.MD and here is a custom example: Add spaces to Mathematica comment delimiters?

v0.7.0 (21-02-2018) support for V10.4

As of v0.7.0 code templates will work on V10.4, probably even in earlier versions but I need to check that.

For pre V11 a notebook approach is used instead of an AttachedCell based menu. To enable attached cell method in earlier versions you can run

CurrentValue[$FrontEnd, {TaggingRules, "DevTools", "MenuMethod"}] = "Cell" (*or "Notebook" *) 

but FE crashed for me once or twice and I was not able to reproduce circumstances so do it on your own risk.
