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.
Keyboard commands for scrolling the text area are also available.
View>Scrolling>Scroll to
Current Line (shortcut: C+e C+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: C+e C+n
)
moves the caret to the
line in the middle of the screen.
View>Scrolling>Line
Scroll Up (shortcut: C+QUOTE
)
scrolls the text area up by one line.
View>Scrolling>Line
Scroll Down (shortcut: C+SLASH
) scrolls the
text area down by one line.
View>Scrolling>Page
Scroll Up (shortcut: A+QUOTE
) scrolls the text
area up by one screenful.
View>Scrolling>Page
Scroll Down (shortcut: A+SLASH
) 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.
