Commenting

Vem provides comment/uncomment support for most programming languages thanks to the NERD Commenter plugin.

To comment and uncomment pieces of code, use:

v:

toggle comment

Your file type will be detected and the correct commenting symbols applied. This is a toggling action which means that pressing v once will comment out code and pressing it again will uncomment it.

If there is an active selection, all lines of the selection will be commented out, otherwise only the current line will —which is very practical for quickly comment/uncomment single lines.

For example, in C++, pressing v with this piece of code selected will produce:

// idVec3 idPlayer::colorBarTable[ 5 ] = {
//     idVec3( 0.25f, 0.25f, 0.25f ),
//     idVec3( 1.00f, 0.00f, 0.00f ),
//     idVec3( 0.00f, 0.80f, 0.10f ),
//     idVec3( 0.20f, 0.50f, 0.80f ),
//     idVec3( 1.00f, 0.80f, 0.10f )
// };

Block comments

By default, Vem uses line comments whenever possible, but you can instruct it to mark a block of code with block comment symbols using:

V:

comment code using block comment symbols (eg. /* */ )

For example, commenting code out in C++ would result in:

/* idVec3 idPlayer::colorBarTable[ 5 ] = {
    idVec3( 0.25f, 0.25f, 0.25f ),
    idVec3( 1.00f, 0.00f, 0.00f ),
    idVec3( 0.00f, 0.80f, 0.10f ),
    idVec3( 0.20f, 0.50f, 0.80f ),
    idVec3( 1.00f, 0.80f, 0.10f )
}; */

Note that to uncomment a piece of code surrounded by block comment symbols you need to use v. V doesn't have the same toggling behaviour as v because it can be used to nest block comments.
