how can I get all the abbreviations of vim's options?

Question

Such as I can use

:set nu

as

:set number

Where can I get the whole list of this kind of mapping (number -> nu

Answer 1

In the help it shows you the minimum amount required. But in general, you only need enough to be unique. So :set numb is fine too.

See in the help how the [mber] is in square brackets? That means it's not necessary.

:[range]nu[mber] [count] [flags]
            Same as :print, but precede each line with its line
            number.  (See also 'highlight' and 'numberwidth'
            option).
            See |ex-flags| for [flags].

Note: vim thinks of 'abbreviations' as something different - see :help abbreviations which describes how you can save time entering words.
