CAPS Warn is designed for
people who type
with one hand using Sticky Keys, or for anyone who presses the Caps
Lock key frequently by mistake.
is a Preference
Pane that provides:
- on-screen indications of when the Caps Lock,
Shift, Function (Fn), Control, Option, or Command keys are pressed (or
stuck on by Sticky Keys) . You can chose from among three types
of visible indications:
- An arrow in the menu bar that turns red when the
keys you choose are pressed.
- Alarge almost transparent image in the center of
your screen when the keys you choose are pressed.
- A square block to the left of the Apple in
the menu bar that can show when all modifiers are pressed.
The warning can be specified to be continous while CAPS LOCK or NUM
LOCK is on. This continuous feature applies only to sound
warnings and only if you choose a sound other than the system alert
- you have
on the CAPS Lock and/or
- you have typed a
number (default 5) of keys with the SHIFT key (or Sticky Keys SHIFT) or
CAPS Lock and/or you have turned on the Num Lock. CAPS Warn warns you
regardless of what application you are typing into.
The CAPS Warn preference
pane appears above with the default settings shown.
If you show the icon in the menu bar, selecting the icon
displays a menu that allows you to open the preference pane.
The Volume Control is enabled only in 10.5+, and only if
you choose a sound other than the system alert sound (the volume for
the system alert sound is specified in the Sound system preference).
to be able to warn you about multiple shifted key
presses, you must enable assistive device access in the System
Preferences. Exactly how this is done depends on which version of the
Mac OS you are running. Instructions for the version you are
running will appear in the CAPS Warn preference pane.
Enabling CAPS Warn via
Preference Pane will automatically disable any previous version
of CAPS Warn.
(shown at the right) allows you
- which applications should be excluded when counting
mutiple caps typed.
- what keys or words should be excluded when counting
The Updates tab allows you to
specify automatic checking for updates. Going to the tab will
also check for updates, allowing you to download an update if available.
The Register tab allows you
to check for and or enter a purchased registration code.
CAPS Warn is a MacOS X
It runs on Yosemite (10.10) as well, but Apple has a bug
that may make you think it does not. If you want to use the "Warn
me after typing multiple keys with SHIFT or CAPS LOCK" option, then you
must enable the CAPS Warn Helper application in the Accessibility
panel of the Security and Privacy System Preference.
There is a bug in that panel that prevents Caps Warn Helper
from being visible so you can enable it. To work around this bug,
use the following procedure:
- Click on the + symbol in the Security
& Preferences -> Accessibility panel. A choose
file dialog appears.
- In the Finder, hold down the Option key,
click on Go, and choose Library.
- Inside the Library folder, open the PreferencePanes
- Right-click (or control-click) Caps
Warn.prefPane and choose “Show Package Contents”.
- Open the Contents folder.
- Open the Resources folder.
- In there you will find Caps Warn Helper.
- Drag it to the choose file dialog.
You will see no change in the Accesibility panel, but
Caps Warn will now work after re-enabling it.
