Some Fundamentals &kwrite; and many other &katepart; users are very simple to use. Anyone that has used a text editor should have no problems. Drag and Drop &katepart; uses the &kde; Drag and Drop protocol. Files may be dragged and dropped onto &katepart; from the Desktop, the filemanager &dolphin;, or some remote &FTP; site opened in one of &dolphin;'s windows. Shortcuts Many of the shortcuts are configurable by way of the Settings menu. By default &katepart; honors the following shortcuts: &Ins; Toggle between Insert and Overwrite mode. When in insert mode the editor will add any typed characters to the text while pushing along any data to the right of the text cursor. Overwrite mode causes the entry of each character to eliminate the character immediately to the right of the text cursor. &Left; Move the cursor one character to the left &Right; Move the cursor one character to the right &Up; Move the cursor up one line &Down; Move the cursor down one line &Ctrl;E Go to previous editing line &Ctrl;&Shift;E Go to next editing line &Alt;&Shift;&Up; Move cursor to previous matching indent &Alt;&Shift;&Down; Move cursor to previous matching indent &Ctrl;6 Move to Matching Bracket &PgUp; Move the cursor up one page &PgDn; Move the cursor down one page &Home; Move the cursor to the beginning of the line &End; Move the cursor to the end of the line &Ctrl;&Home; Move to Beginning of Document &Ctrl;&End; Move to End of Document &Ctrl;&Up; Scroll Line Up &Ctrl;&Down; Scroll Line Down &Ctrl;&Right; Move Word Right &Ctrl;&Left; Move Word Left &Ctrl;&Shift;&Up; Move Lines Up &Ctrl;&Shift;&Down; Move Lines Down &Ctrl;&Alt;&Up; Duplicate Selected Lines Up &Ctrl;&Alt;&Down; Duplicate Selected Lines Down &Ctrl;B Set a Bookmark &Alt;&PgUp; Previous Bookmark &Alt;&PgDn; Next Bookmark Delete the character to the right of the cursor (or any selected text) &Backspace; Delete the character to the left of the cursor &Ctrl;∇ Delete Right Word &Ctrl;&Backspace; Delete Left Word &Ctrl;K Delete Line &Shift;&Enter; Insert newline including leading characters of the current line which are not letters or numbers.
