Vim Help Topics: Modes, Key Combinations, Regex, Registers, Scripting, Mappings, Commands, and Window Management

with v_. Help for jumping to the other side of the Visual area: > :help v_o 7) Command line editing and arguments start with c_. Help for using the command argument %: > :help c_% 8) Ex-commands always start with ":", so to go to the ":s" command help: > :help :s 9) Commands specifically for debugging start with ">". To go to the help for the "cont" debug command: > :help >cont 10) Key combinations. They usually start with a single letter indicating the mode for which they can be used. E.g.: > :help i_CTRL-X < takes you to the family of CTRL-X commands for insert mode which can be used to auto-complete different things. Note, that certain keys will always be written the same, e.g. Control will always be CTRL. For normal mode commands there is no prefix and the topic is available at :h CTRL-<Letter>. E.g. > :help CTRL-W < In contrast > :help c_CTRL-R < will describe what the CTRL-R does when entering commands in the Command line and > :help v_CTRL-A < talks about incrementing numbers in visual mode and > :help g_CTRL-A < talks about the "g<C-A>" command (e.g. you have to press "g" then <CTRL-A>). Here the "g" stands for the normal command "g" which always expects a second key before doing something similar to the commands starting with "z". 11) Regexp items always start with /. So to get help for the "\+" quantifier in Vim regexes: > :help /\+ < If you need to know everything about regular expressions, start reading at: > :help pattern.txt 12) Registers always start with "quote". To find out about the special ":" register: > :help quote: 13) Vim Script is available at > :help eval.txt < Certain aspects of the language are available at :h expr-X where "X" is a single letter. E.g. > :help expr-! < will take you to the topic describing the "!" (Not) operator for Vim Script. Also important is > :help function-list < to find a short description of all functions available. Help topics for Vim script functions always include the "()", so: > :help append() < talks about the append Vim script function rather than how to append text in the current buffer. 14) Mappings are talked about in the help page :h |map.txt|. Use > :help mapmode-i < to find out about the |:imap| command. Also use :map-topic to find out about certain subtopics particular for mappings. e.g: > :help :map-local < for buffer-local mappings or > :help map-bar < for how the '|' is handled in mappings. 15) Command definitions are talked about :h command-topic, so use > :help command-bar < to find out about the '!' argument for custom commands. 16) Window management commands always start with CTRL-W, so you find the corresponding help at :h CTRL-W_letter. E.g. > :help CTRL-W_p < for moving the previous accessed window. You can also access > :help windows.txt < and read your way through if you are looking for window handling

This section provides guidance on accessing Vim's help system for various features. It covers visual mode (v_), command-line editing (c_), ex-commands (:), debugging commands (>), and key combinations with CTRL. It further explains how to find help on regular expressions (/), registers (quote), Vim script (eval.txt), mappings (map.txt), command definitions (command-topic), and window management commands (CTRL-W).
