Navigating Around the Text Editor
The caret marks the current position.
The caret is a vertical bar displayed before the current character when the insert mode is true. Conversely, it is an underline displayed under the current character when the insert mode is false.
This section contains the following topics.
Using the Mouse within the Editor Text Area
The mouse actions that you can perform in the text area of the JadeTextEdit control text editor are listed in the following table.
| Mouse Action | Result |
|---|---|
| Left-click | Moves the caret (insertion point) to the cursor location and cancels the selection |
| Double-click | Selects the word at the cursor location |
| Triple-click | Selects the line at the cursor location |
| Left down and move | Anchors the selection at the down position and extends to follow the cursor location |

| Shift+left-click | Moves the caret (insertion point) to the cursor location and extends the selection to the new location |
| Alt+left down and move | Anchors a rectangular selection at the down position and extends to follow the cursor location |
Using the Mouse within the Line Number Margin
The mouse actions that you can perform within the line number margin of the JadeTextEdit control text editor are listed in the following table.
| Mouse Action | Result |
|---|---|
| Left-click | Selects the line at the cursor location |
| Ctrl+left-click | Selects all text in the text editor |
| Shift+left-click | Extends the line-based selection from the current anchor point to the line at the cursor location |

| Ctrl+Shift+left-click | Toggles (expands or contracts) the fold point and all lower-level (child) fold points to match |

Using the Keyboard in the Text Editor
The keyboard and shortcut commands in the JadeTextEdit control follow standard conventions. All move keys (that is, arrows, Page Up, Page Down, Home, and End keys) enable the extension or reduction of the stream selection when holding down the Shift key and of the rectangular selection when holding the Shift and Alt keys.
The setting of the wrapMode property changes the behavior of the Home key. When the value of the wrapMode property is SC_WRAP_WORD, the Home key moves the caret to the start of the text line rather than to the start of the display line.
In addition to the keyboard zoom functionality commands listed in the following table, you can use the Ctrl key and the mouse to increase, decrease, or restore text size; that is, Ctrl+ scrolling the mouse wheel forward increases the zoomed size, Ctrl+ scrolling the mouse wheel backward decreases the zoomed size, and Ctrl+ clicking the middle mouse button (pressing the mouse wheel) restores the editor pane to normal.
The keyboard commands are listed in the following table.
