See the comprehensive list of key +commands in the [appendix](14_Appendix.html#key_bindings). Key commands can be +modified in your [preferences](9_Preferences.html#key_commands). + +## Character Autopairing + +Usually, quote (`'`, `"`) and brace (`(`, `[`, `{`) characters go together in +pairs. By default, Textadept automatically inserts the complement character when +the first is typed. Similarly, the complement is deleted when you press +`Backspace` over the first. See the +[preferences](9_Preferences.html#module_settings) page if you would like to +disable this. + +## Word Completion + +Textadept provides buffer-based word completion. Start typing a word, press +`Ctrl+Return` (`Esc` on Mac OSX), and a list of suggested completions based on +words in the current document is provided. Continuing to type changes the +suggestion. Press `Return` to complete the selected word. + +![Word Completion](images/wordcompletion.png) + +## Find and Replace + +`Ctrl+F` (`Apple+F` on Mac OSX) brings up the Find/Replace dialog. In addition +to offering the usual find and replace, Textadept allows you to find with [Lua +patterns](14_Appendix.html#lua_patterns) and replace with Lua captures and even +Lua code! For example: replacing all `(%w+)` with `%(string.upper('%1'))` +capitalizes all words in the buffer. Lua captures (`%n`) are only available from +a Lua pattern search, but embedded Lua code enclosed in `%()` is always allowed. + +#### Find in Files + +Find in Files (`Apple+Shift+F` on Mac OSX) will prompt for a directory to +search. The results are displayed in a new buffer. Double-clicking a search +result jumps to it in the file. Replace in Files is not supported. You will have +to `Find in Files` first, and then `Replace All` for each file a result is found +in. The `Match Case`, `Whole Word`, and `Lua pattern` flags still apply. + +![Find in Files](images/findinfiles.png) + +#### Find Incremental + +You can start an incremental search by pressing `Ctrl+Shift+F` (`Apple+I` on Mac +OSX). Incremental search searches the buffer as you type. Only the `Match Case` +option is recognized. + +#### Replace in Selection + +By default, `Replace All` replaces all text in the buffer. If you want to +replace all text in just a portion of the buffer, select a block of text and +then `Replace All`. + +## Indentation + +#### Increase or Decrease Indent Level + +The amount of indentation for a selected set of lines is increased by pressing +`Tab` and decreased by pressing `Shift+Tab`. Using these key sequences when no +selection is present does not have the same effect. + +#### Change Indent Size + +The indent size is usually set by a [language-specific +module](7_Modules.html#buffer_properties) or the [theme](8_Themes.html#buffer). +Textadept shows what it is using for indentation in the document statusbar. + +![Document Statusbar](images/docstatusbar.png) + +#### Using Tabs Instead of Spaces + +You can use tabs instead of the default spaces by pressing `Ctrl+T, V, Tab` +(Apple+T, V, Tab on Mac OSX) or using the `Buffer -> Toggle Use Tabs` menu. +Textadept shows what it is using for indentation in the document statusbar. + +The default option is usually set by a [language-specific +module](7_Modules.html#buffer_properties) or the [theme](8_Themes.html#buffer). + +#### Converting Between Tabs and Spaces + +Use the `Edit -> Convert Indentation` menu to convert indentation. If the buffer +is using tabs, all spaces are converted to tabs. If the buffer is using spaces, +all tabs are converted to spaces. + +## Selecting Text + +#### Rectangular Selection + +Holding `Alt+Shift` (`Apple+Shift` on Mac OSX) and pressing the arrow keys +enables rectangular selections to be made. Start typing to type on each line. + +![Rectangular Selection](images/rectangularselection.png) +     +![Rectangular Edit](images/rectangularselection2.png) + +#### Multiple Selection + +Clicking the mouse at a point in the buffer while holding `Control` places an +additional caret at that point. Clicking and dragging while holding `Control` +creates multiple selections. Start typing to enter text at each selection. + +#### Selecting Entities + +Textadept allows you to select many different entities from the caret. `Alt+S` +(`Ctrl+S` on Mac OSX) is the key prefix to entity selection. Typing `'`, `"`, +`(`, `[`, or `{` selects all text between the matching delimiters. Typing `W`, +`L`, `P`, `B`, or `S` (without holding `Shift`) selects the current word, line, +paragraph, indented block, or style respectively. Typing `T` selects the text +between `>` and `<`, useful for selecting within HTML tags. Typing `G` grows the +current selection by one character to each side, so `Alt+S, "` followed by +`Alt+S, G` selects an entire `""` sequence instead of just the text in-between +quotes. Finally, typing `C` followed by any other character selects all text +between a pair of those characters. `Alt+S, C, "` is identical to `Alt+S, "`. + +## Enclosing Text + +As a complement to selecting entities, you can enclose text as entities. The +key prefix is `Alt+C` (`Ctrl+C` on Mac OSX). Typing `'`, `"`, `(`, `[`, or `{` +encloses the text in the appropriate character pair. Typing `T` (without holding +`Shift`) creates an opening and closing HTML tag while `Shift+T` creates a +single HTML tag. Finally, typing `C` followed by any other character encloses +the text between a pair of those characters. `Alt+C, C, "` is identical to +`Alt+C, "`. + +If no text is selected, the word to the left of the caret is enclosed. + +## Word Highlight + +All occurances of a given word are highlighted by putting the caret over the +word and pressing `Ctrl+H` (`Ctrl+Apple+T` on Mac OSX). This is useful to show +occurances of a variable name in source code. + +![Word Highlight](images/wordhighlight.png) + +## Editing Modes + +#### Virtual Space + +Virtual space (freehand) mode is enabled and disabled with `Ctrl+T, V, V` +(`Apple+T, V, V` in Mac OSX). When enabled, caret movement is not restricted by +line endings. + +#### Overwrite + +Overwrite mode is enabled and disabled with the `Insert` key. When enabled, +characters in the buffer will be overwritten instead of inserted as you type. +The caret also changes to an underline when in overwrite mode. -- cgit v1.2.3
