User Defined Syntax HighlightingIt allows user to define his own language : not only the syntax highlighting keywords, but also the syntax folding keywords, comment keywords and the operators. ( screenshot1, screenshot2, screenshot3, screenshot4 ).
Auto-completionFor most supported languages, user can make his/her own API list (or download the api files from dowload section). Once the api file is ready, type Ctrl+Space to launch this action (see screenshot). For more information about Auto-completion, please see Auto-completion HOWTO.
Multi-DocumentYou can edit several documents at the same time.
Multi-ViewYou have two views at same time. That means you can visualize (edit) 2 different documents at the same time (screenshot). You can visualize (edit) in the 2 views one document at 2 different positions as well. The modification of document in one view will carry out in another view (i.e. you modify the SAME document when you are in clone mode).
Regular Expression Search/Replace supportedYou can search and replace one string in the document by using the regular expression.
Full Drag 'N' Drop supportedYou can open a document by drag & drop. You can also move your document from a position (or even a view) to another by drag & drop.
Dynamic position of ViewsThe user can set the position of the views dynamically (only in 2 views mode : the splitter can be set in horizontal or in vertical), see screenshot.
File Status Auto-detectionIf you modify or delete a file which opened in Notepad++, you will be notified to update your document (reload the file or remove the file).
Zoom in and zoom outThat's another fantastic function of Scintilla component. Just see screenshot.
