Java Reference
In-Depth Information
Although you can't disable a color scheme property, you can achieve the
same effect by deselecting all three of the style color options. For exam-
ple, if you don't want the current row highlighted, deselect the
Caret
row
property's background option. Doing so causes this property's font to re-
vert to the default text style and background.
TIP
You can also select a text effect, also known as
text decoration
, for your color
scheme property by enabling the
Effects
option and selecting one of the follow-
ing effects from the drop-down:
Underscored
—Basic underlined text with a straight underscore in the
selected color
■
Underwaved
—Alternative underlining with a rippled underscore in the
selected color
■
Bordered
—Solid border in the selected color around the element on all
four sides
■
Strikeout
—Line of the selected color through the center of the text
■
To choose a color, click an entry in the color palette to the right of each option.
The currently selected color is shown in the larger square to the property's imme-
diate right. Double-click this square to choose a color from the color wheel.
These non-color-based visual effects are extremely useful for drawing at-
tention to code that needs attention, sometimes in unforeseen ways.
We've known at least two software developers with red-green color blind-
ness who, using
IDEA
's highly configurable color and fonts settings, were
able to demarcate errors and warnings using underscored, underwaved,
bordered, and struck-out text. Doing so allowed them to enjoy the full
range of
IDEA
's contextual code analysis.

12.4 Customizing keyboard shortcuts
One of
IDEA
's strong suits is its keyboard support.
IDEA
provides keyboard access
to just about every feature in its arsenal and also lets you customize them to your
liking. If you wish, you can use
IDEA
almost entirely from the keyboard, never
having to touch your grubby little mouse. This lets you keep your hands on the
keyboard, where they belong! (You can't code with the mouse, after all.) Once you
start navigating with the keyboard, you'll quickly find it more efficient than con-
stantly reaching for the mouse.
