method
(send a-keymap:aug-keymap get-chained-keymaps)
→ (listof (is-a?/c keymap%)) Returns the list of keymaps that are chained to this one.
method
(send a-keymap:aug-keymap get-map-function-table) → hash?
Returns a hash-table that maps symbols naming key sequences to the names of the keymap functions the are bound to.
method
(send a-keymap:aug-keymap get-map-function-table/ht ht) → hash?
ht : hash? This is a helper function for get-map-function-table that returns the same result, except it accepts a hash-table that it inserts the bindings into. It does not replace any bindings already in ht.

method
(send a-keymap:aug-keymap chain-to-keymap next prefix?) → void next : (is-a?/c keymap%) prefix? : boolean? Overrides chain-to-keymap in keymap%.Keeps a list of the keymaps chained to this one.
method
(send a-keymap:aug-keymap remove-chained-keymap keymap) → void
keymap : (is-a?/c keymap) Overrides remove-chained-keymap in keymap%.Keeps the list of the keymaps chained to this one up to date.

Before calling this procedure, the function append-editor-operation-menu-items is called.
parameter
→ (-> (is-a?/c popup-menu%) (is-a?/c editor<%>) (is-a?/c event%) void?) (keymap:add-to-right-button-menu/before proc) → void? proc : (-> (is-a?/c popup-menu%) (is-a?/c editor<%>) (is-a?/c event%) void?) 
After calling this procedure, the function append-editor-operation-menu-items is called.
procedure
(keymap:call/text-keymap-initializer thunk-proc) → any/c

procedure

procedure

procedure
(keymap:get-user) → (is-a?/c keymap%)
procedure
(keymap:get-global) → (is-a?/c keymap%)

procedure
(keymap:make-meta-prefix-list key [ mask-control?]) → (listof string?) key : string? mask-control? : boolean? = #f 
procedure
(keymap:send-map-function-meta keymap key func [ mask-control? #:alt-as-meta-keymap alt-as-meta-keymap]) → void? keymap : (is-a?/c keymap%) key : string? func : string? mask-control? : boolean? = #f alt-as-meta-keymap : (or/c (is-a?/c keymap%) #f) = #f 
This procedure binds all of the key-bindings obtained by prefixing key with a meta-prefix to func in keymap.
If alt-as-meta-keymap is a keymap% object, then the the key binding (string-append "?:a:" key) is bound to func in alt-as-meta-keymap. Additionally, if func has not been added (via keymap%) to alt-as-meta-keymap, then keymap:send-map-function-meta signals an error.

- ring-bell (any events) — - Rings the bell (using bell) and removes the search panel from the frame, if there. 
- save-file (key events) — - Saves the buffer. If the buffer has no name, then finder:put-file is invoked. 
- save-file-as (key events) — - Calls finder:put-file to save the buffer. 
- find-string (key events) — - Opens the search buffer at the bottom of the frame, unless it is already open, in which case it searches for the text in the search buffer. 
- find-string-reverse (key events) — - Same as “find-string”, but in the reverse direction. 
- find-string-replace (key events) — - Opens a replace string dialog box. 
- toggle-anchor (key events) — - Turns selection-anchoring on or off. 
- center-view-on-line (key events) — - Centers the buffer in its display using the currently selected line. 
- collapse-space (key events) — - Collapses all non-return whitespace around the caret into a single space. 
- remove-space (key events) — - Removes all non-return whitespace around the caret. 
- collapse-newline (key events) — - Collapses all empty lines around the caret into a single empty line. If there is only one empty line, it is removed. 
- transpose-chars (key events) — - Transposes the characters before and after the caret and moves forward one position. 
- transpose-words (key events) — - Transposes words before and after the caret and moves forward one word. 
- capitalize-word (key events) — - Changes the first character of the next word to a capital letter and moves to the end of the word. 
- upcase-word (key events) — - Changes all characters of the next word to capital letters and moves to the end of the word. 
- downcase-word (key events) — - Changes all characters of the next word to lowercase letters and moves to the end of the word. 
- goto-line (any events) — - Queries the user for a line number and moves the caret there. 
- goto-position (any events) — - Queries the user for a position number and moves the caret there. 
- copy-clipboard (mouse events) — - Copies the current selection to the clipboard. 
- cut-clipboard (mouse events) — - Cuts the current selection to the clipboard. 
- paste-clipboard (mouse events) — - Pastes the clipboard to the current selection. 
- copy-click-region (mouse events) — - Copies the region between the caret and the input mouse event. 
- cut-click-region (mouse events) — - Cuts the region between the caret and the input mouse event. 
- paste-click-region (mouse events) — - Pastes the clipboard into the position of the input mouse event. 
- select-click-word (mouse events) — - Selects the word under the input mouse event. 
- select-click-line (mouse events) — - Selects the line under the input mouse event. 
- start-macro (key events) – Starts recording a keyboard macro
