The Visual Settings submenu. The first
entries are dedicated to language, code
page, font, and symbols, while the rest
of the entries are used to specify the
text and background colors of the
different information items. Note that
the font settings apply to menus only,
not to OSD text.

confirmation is not required. Simply leave the menu by pressing the
or ALT button when you are finished.
Some entries have a large value range and dialing in the desired value
with the
CHDK programmers have equipped such entries with a child entry named
Value Factor that usually has the values Off, 1, 10, 100, etc. The value se-
lected here is multiplied by the value of the parent entry. For example, if
you dialed in a value of 40 for the entry Override ISO Value
selected a value of 10 in the child entry Value Factor, you would be specify-
ing an ISO speed of 40*10 = 400. Selecting the value Off in the Value Factor
disables the parent entry. In this example, selecting Off for Value Factor
would switch off the manual override of the ISO speed and return to the
camera's native ISO speed control system.

Customizing the user interface

The CHDK has many functions to customize the user interface. Most of
these functions are found in the submenu Visual Settings. Here you can
change the language of the CHDK menus. (The language of the native
camera menus is changed separately. Consult your camera's user manual
to do so.) You can change the OSD Codepage to allow for different national
characters. You can also select between plain, bold, serif, and sans serif
fonts in different sizes, and switch between differently sized symbols (10 or
16 pixels).

4.2.1 OSD Codepage

By default, the CHDK is set up with the OSD Codepage Win1251 that sup-
ports the Cyrillic alphabet (the CHDK was originally created by a Russian
programmer).
For English, Spanish, or other Western languages, switch the codepage
to Win1252. Invoke

4.2.2 Fonts

By default, the CHDK uses the smallest font available for its menus, thus
maximizing the number of menu items displayed on one page. Depending
on your eyesight, you may want to select a larger font. For me, this has very
much increased the joy of using the CHDK. Invoke
LEFT or RIGHT button would be very tedious indeed. Therefore, the
