Open a new file
Use the file menu or double click on this file in a file browser.

Create a file or folder
Use the [new] button at the bottom right of a file browser. Type a filename with an extension or a folder name without an extension.

Save a file
Use the save button at the top right of a code editor.

File outlines
File outlines make it easy to check the structure of a source file. This works with many languages. To activate it, use the view button (top left of a code editor). If you always want to work from the outline, select ’show outline first’ in [view] menu.
You can double click on any element in the outline and this will pop up a code editor.

A few key shortcuts
CONTROL+H
search all files in the currently selected directory
CONTROL+UP
keyboard navigation
CONTROL+DOWN
find instances of the keyword pointed at by the blinking caret (hyper navigation). This will also provide suggested spellings when an identifier is not recognised (yellow highlights)

How does consistency check work?
[FEATURE UNDER REVIEW - CURRENTLY UNAVAILABLE]
Consistency check helps avoiding incorrectly spelled keywords and other unknown identifiers.
This simply works by checking how many instances of a word are in the current file. If only one instance is found, it will be highlighted in yellow.
Note that this doesn’t always mean there is something wrong. Often, however, this indicates that the keyword may be spelled incorrectly, or that a class needs to be imported.
To avoid getting bogged down with too many warnings, consistency check only covers what you type after a file has been loaded – also, if you are sure a keyword is correct, justs leave it as it is and consistency check will ignore it after a while.

Using the command line tool
In [view] menu, select show/hide console to activate the command line tool (or press CONTROL+R).
Type the command you want to run near the [run] button, then press [run] or ENTER. You can also select a target directory.
The command line tool uses a history. You can use the UP/DOWN keys to browse the history and repeat a command. This is similar to most ‘black screen’ UNIX or DOS terminals.
