Setting colors and fonts

Word completion

Word completion is useful when the classes or fields being used are not already created. Press Ctrl + Enter while typing the class or field name for the second time. This displays all the words beginning with that character one after another. Select the required word, release the keys to complete the word automatically. For example, type QueueConnerctionFactory and at the next usage, type Q and press Ctrl + Enter. The word is completed as QueueConnectionFactory.

Line completion

Type one or more initial characters of the line of code to be completed and press Ctrl + K. This displays all possible lines one after another. On reaching the required line of code, release the keys to complete the line automatically. The cursor is placed at the end of the sentence.

This feature is useful in case of long import statements and multiple variable declarations.

Joining lines

Place the cursor at the beginning or end of a line in the open file. Press Ctrl + J to join the next line to the selected line.

Viewing open files

Select View > Show Open File(s) or press Shift + F11.

It displays the names of all open files in a panel. Single click on the name of a file displays it in the Display Panel. Another alternative to move between open files is to press Ctrl + Tab. On Linux, to move between open files press Ctrl + Tab, release them and press Ctrl key again.

Introducing a newline

Press Shift + Enter to introduce a new line after the current line and set the caret position in the newline. Press Ctrl + Enter to introduce a newline at the caret position with out moving the caret.

Saving untitled files

Studio intelligently saves an untitled file by considering the absolute path of the open desk and module, currently open in the Editor. A node for the new file is created in the desk tree.

This eliminates the need to save an untitled file at a temporary location and import it later into a desired location under a desk.

Reopening last used files on Studio restart

Studio remembers all the last opened files; all desks and files that were open in the Editor before, are reopened automatically on Studio restart. The last used file is made the current file. The view-port and location of the caret are same as before.

Caret position in a file

When a file is closed, Editor remembers the caret position. On reopening the file, the view-port and location of caret are the same as they were when the file was last closed.

If there is no selection in the Editor and a cut (Ctrl + X) or copy (Ctrl + C) operation is performed, it is applied to the current line.

Using Incremental search

Select a desk node in the explore panel and type the string to be searched for. As each character is typed, the search proceeds to the next occurrence of the string in the open tree structure in the explore panel as specified so far. Press Enter or Return to open the required file. Typing a word which has no match makes the text appear red.

Adding, removing, and navigating between bookmarks

Bookmarks are placed on lines for easy manoeuvrability between lines. Place the cursor at a suitable position, select Search > Add/ Remove Bookmarks or press Ctrl + B. A bookmark corresponding to the line is introduced into the gutter.

Use Search menu option or press F2 to take the control to the next bookmark in the file. The cursor is placed at the beginning of the line. To take control to the previous bookmark, use Search menu option or press Shift + F2.

The cursor is placed at the beginning of the line.

Regular expressions are specialized sets of patterns available to specify a set of possible strings that can be matched with other patterns. Studio Editor provides the following characters to be used as Regular Expressions for matching patterns.
