Scrolling

View>Scrolling>Scroll to Current Line (shortcut: Control-E Control-J) scrolls the text area in order to make the caret visible, if necessary. It does nothing if the caret is already visible.

View>Scrolling>Center Caret on Screen (shortcut: Control-E Control-I) moves the caret to the line in the middle of the screen.

View>Scrolling>Line Scroll Up (shortcut: Control-') scrolls the text area up by one line.

View>Scrolling>Line Scroll Down (shortcut: Control-/) scrolls the text area down by one line.

View>Scrolling>Page Scroll Up (shortcut: Alt-') scrolls the text area up by one screenful.

View>Scrolling>Page Scroll Down (shortcut: Alt-/) scrolls the text area down by one screenful.

The above scrolling commands differ from the caret movement commands in that they don't actually move the caret; they just change the scroll bar position.

View>Scrolling>Synchronized Scrolling is a check box menu item. If it is selected, scrolling one text area in a split view will scroll all other text areas in the view. Has no effect if the view is not split.

Mouse Wheel Scrolling

If you have a mouse with a scroll wheel and are running Java 2 version 1.4, you can use the wheel to scroll up and down in the text area. Various modifier keys change the action of the wheel:

  • Shift - scrolls an entire page at a time.

  • Control - scrolls a single line at a time.

  • Alt - moves the caret up and down instead of scrolling.

  • Alt-Shift - extends the selection up and down instead of scrolling.
