New [Command + N] Creates a new document. The lines with slashes are commented out and are only visible for you as the developer. If the document which was the visible one before creating had no name nor changes of the default values, it will be overwritten. You can have up to 6 open documents at the same time.
Open... [Command + O] Launches the file chooser so that you can select a document to open. You can't open two instances of the same document (ParseProGo wouldn't know which one to store). Default directory is your workspace; possible suffixes are '.html', '.htm', '.css', '.js', '.svg', '.txt', '.php', '.php3', '.php4', '.php5', '.php6'. To open other documents, change the suffix in the Finder first (notice that ParseProGo can only handle text-based files). ParseProGo's file system can open almost everything, but the text field will only display documents whether they are encoded as UTF-8 or don't contain special characters; this should be no problem for you because ParseProGo (and most other good applications) saves files encoded as UTF-8. If the document to open is located outside the workspace, it will be opened as template (this is not an error: for to be parsed as PHP, it must be located inside the workspace). If the document which was the visible one before opening had no name nor changes of the default values, it will be overwritten. You can have up to 6 open documents at the same time.
Open Recent Opens one of the last 5 documents you worked with. If the file has been renamed, moved, or deleted, ParseProGo won't (of course) be able to find it. Using Open Recent, ParseProGo will ignore the restrictions of Open - some developers want this freedom, although I can't see the sense of it.
Close [Command + W] Closes the visible document. If there are unsaved changes, you will be asked first.
Save
[Command + S]
Saves the visible document with given name at given path. If path or title are not set, you will be lead to
Save As... [Command + Shift + S] Launches the file chooser so that you can select a path, a title and a suffix for your open document, and stores it using UTF-8 as encoding. If the open document already has a name and a storing-location inside the workspace, the original will not be altered, and the reference is set to the actual copy. You can overwrite an existing file but you will be asked first. ParseProGo will accept your decision, but only files described in Open can be opened. Be careful with special characters in file names: ParseProGo can deal with that, but most servers (and a lot of web-browsers) can't.
Revert Reverts to the last saved version of the visible document. To avoid misunderstandings, you will be asked first.
Print... [Command + P] Prints your document, the parsed result, or the highlighted file, depending on where you put the focus on. To get best results, use Print -> Preview, and eventually alter the values in Page Setup...
