The value of an option (for example ic) |
If a function is declared with
range, the the special variables
a:firstline and
a:lastline give
the numbers where the selection starts and ends.
Additionally, the value of an option can be set/gotten by preceding the option name with a & (For example &shell
or &term).
The value of environment variables can be gotten by preceding the variable's name with a $ (For example $VIM).
@/ is the value of the last search pattern. This value can be
assigned to.
