mapping keys

points of interest

for help see ':help mapping' in vim

typical syntax:

:mappingcommand [special arguments] {lhs} {rhs}

example:
" this sets F3 to toggle line wrapping
:map <F3> :set wrap!<CR>

[type]noremap is often used to redefine a command to avoid nested and recursive mappings

there are five sets of mappings:

:map  (Normal, Visual+Select, Operator-Pending)
:nmap (Normal, when vim is waiting for any key to be a command)
:vmap (Visual, when a visual selection has begun)
:omap (Operator-pending mode, after "d", "y", "c", etc...)
:imap (Insert mode, when you are typing characters)
:cmap (Command-line mode, when entering a ":" or "/" command)

to remove a key mapping:

unmap
nunmap
vunmap
ounmap
iunmap
cunmap

on the Mac, the command key is mapped as <D- >
to view a list of current mappings:
```
:map
```
to view a list of current mappings and the last place each item was set from:
```
:set verbose=1
:map
```
on the Mac the pasteboard (clipboard) is at register “*

troubleshooting

if you are using gvim in windows, and you lose your ability to cut/copy/paste with Control-X,C, and V, you probably had the carriage returns removed from your vimrc file
- rename your .vimrc file temporarily
- start up gvim and type :mkvimrc ~/.vimrc-default
- compare the listings in this file with your vimrc file and fix as necessary
