CUSTOM FUNCTIONS

Changing Screen Color
You’ve seen the XSi’s default status screen color, but by using the Screen color
command on the first Tools page, you can select a different color scheme—one
that might be easier to read in your current lighting conditions.
e XSi’s four different interface color schemes.
Some screen colors will be easier to read in bright light, while some will be easier
in low light or dark conditions. Experiment with each until you find something
that’s right for your current lighting conditions.
Custom Functions
In Chapter 10, you got a glimpse of the XSi’s custom functions when I discussed
mirror lockup. Custom functions are special commands that you access through
the Custom Functions command on the third tool menu. While there are a few
commands, such as Mirror lockup, that seem more like primary commands that
should be in the normal menu system, the bulk of the custom functions are com-
mands that let you tweak and alter the behavior of other commands.
