All pairs (when not +ignored) will be recorded and can be later displayed with +`general-describe-keybindings'. + +If DEFINER is specified, a custom key definer will be used to bind MAPS. See +general.el's documentation/README for more information. + +Unlike with normal key definitions functions, the keymaps in KEYMAPS should be +quoted (this allows using the keymap name for other purposes, e.g. deferring +keybindings if the keymap symbol is not bound, optionally inferring the +corresponding major mode for a symbol by removing \"-map\" for :which-key, +easily storing the keymap name for use with `general-describe-keybindings', +etc.). Note that general.el provides other key definer macros that do not +require quoting keymaps. + +STATES corresponds to the evil state(s) to bind the keys in. Non-evil users +should not set STATES. When STATES is non-nil, `evil-define-key*' will be +used (the evil auxiliary keymaps corresponding STATES and KEYMAPS will be used); +otherwise `define-key' will be used (unless DEFINER is specified). KEYMAPS +defaults to 'global. There is also 'local, which create buffer-local +keybindings for both evil and non-evil keybindings. There are other special, +user-alterable \"shorthand\" symbols for keymaps and states (see +`general-keymap-aliases' and `general-state-aliases'). + +Note that STATES and KEYMAPS can either be lists or single symbols. If any +keymap does not exist, those keybindings will be deferred until the keymap does +exist, so using `eval-after-load' is not necessary with this function. + +PREFIX corresponds to a key to prefix keys in MAPS with and defaults to none. To +bind/unbind a key specified with PREFIX, \"\" can be specified as a key in +MAPS (e.g. ...:prefix \"SPC\" \"\" nil... will unbind space). + +The keywords in this paragraph are only useful for evil users. If +NON-NORMAL-PREFIX is specified, this prefix will be used instead of PREFIX for +states in `general-non-normal-states' (e.g. the emacs and insert states). This +argument will only have an effect if one of these states is in STATES or if +corresponding global keymap (e.g. `evil-insert-state-map') is in KEYMAPS. +Alternatively, GLOBAL-PREFIX can be used with PREFIX and/or NON-NORMAL-PREFIX to +bind keys in all states under the specified prefix. Like with NON-NORMAL-PREFIX, +GLOBAL-PREFIX will prevent PREFIX from applying to `general-non-normal-states'. +INFIX can be used to append a string to all of the specified prefixes. This is +potentially useful when you are using GLOBAL-PREFIX and/or NON-NORMAL-PREFIX so +that you can sandwich keys in between all the prefixes and the specified keys in +MAPS. This may be particularly useful if you are using default prefixes in a +wrapper function/macro so that you can add to them without needing to re-specify +all of them. If none of the other prefix keyword arguments are specified, INFIX +will have no effect. + +If PREFIX-COMMAND or PREFIX-MAP is specified, a prefix command and/or keymap +will be created. PREFIX-NAME can be additionally specified to set the keymap +menu name/prompt. If PREFIX-COMMAND is specified, `define-prefix-command' will +be used. Otherwise, only a prefix keymap will be created. Previously created +prefix commands/keymaps will never be redefined/cleared. All prefixes (including +the INFIX key, if specified) will then be bound to PREFIX-COMMAND or PREFIX-MAP. +If the user did not specify any PREFIX or manually specify any KEYMAPS, general +will bind all MAPS in the prefix keymap corresponding to either PREFIX-MAP or +PREFIX-COMMAND instead of in the default keymap. + +PREDICATE corresponds to a predicate to check to determine whether a definition +should be active (e.g. \":predicate '(eobp)\"). Definitions created with a +predicate will only be active when the predicate is true. When the predicate is +false, key lookup will continue to search for a match in lower-precedence +keymaps. + +In addition to the normal definitions supported by `define-key', general.el also +provides \"extended\" definitions, which are plists containing the normal +definition as well as other keywords. For example, PREDICATE can be specified +globally or locally in an extended definition. New global (~general-define-key~) +and local (extended definition) keywords can be added by the user. See +`general-extended-def-keywords' and general.el's documentation/README for more +information. + +PACKAGE is the global version of the extended definition keyword that specifies +the package a keymap is defined in (used for \"autoloading\" keymaps) + +PROPERTIES, REPEAT, and JUMP are the global versions of the extended definition +keywords used for adding evil command properties to commands. + +MAJOR-MODES, WK-MATCH-KEYS, WK-MATCH-BINDINGS, and WK-FULL-KEYS are the +corresponding global versions of which-key extended definition keywords.
