Conflicting Extensions

Add-ons, also called plug-ins or extensions, are mini-applications that attach themselves to independent software and add extra capabilities to the program.

Extensions can change a browser's interface, alter the behavior of existing operations, add new functions or install in-browser support for programs like Shockwave Flash or Adobe Reader.

Because these extensions make changes to the overall operation of a browser, they can also affect the shortcut keys.

Most browsers offer an option to run the application with add-ons disabled; if the shortcut keys work when extensions are turned off, one of the add-ons is at fault.

Key Reassignments

Programs like MapKeyboard, SharpKeys and KeyTweak can reassign the functions of each key on the laptop keyboard.

If the computer is running a non standard keyboard layout, certain keys might not behave or respond normally.

For example, if the "Ctrl" key has been disabled or is set to work like "Shift," shortcut keys won't work as expected because the keyboard is no longer using its default mapping.

If the keyboard layout has been changed in the Dell laptop, the registry will contain a Scancode Map entry in

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout or the language bar will show a keyboard language different from the default ("English (United States)," or "EN," for Dell laptops purchased in the U.S.).

Virus Infection

Malicious software can affect the function of peripheral components like the keyboard and mouse.

If the keyboard is exhibiting strange behavior for example, if certain keys do not respond or if keys output unexpected letters a virus is most likely the cause.

Running an anti malware software from within Safe Mode accessed by pressing "F8" on the Dell logo screen should remove any viruses interfering with keyboard response.

Browser Software

Upgrading or downgrading a browser on the PC can affect the Internet shortcut keys associated with that program, especially if the version removes a function that was once associated with a particular keyboard combination.

Alternatively, if you've switched to another browser, you might find that certain shortcuts that worked in the previous browser don't work in the new one.

For example, while "Shift-F10" opens a context menu in Internet Explorer, the same keyboard combination does nothing in Mozilla Firefox.

Hope this helps.

Try pressing both the left and right CTRL keys at the same time and

see if that releases CTRL.

Go to Start / Settings / Control Panel / Accessibility Options /

Keyboard Options.

Turn off CTRL lock if it's on.

If that solves it and to avoid future problems, press "Settings"

Turn off "Press modifier key twice to lock".

Turn on "Turn sticky keys off if 2 keys are pressed at once".

Or turn off "Use shortcut"

Clean your keyboard.

Sounds to me as if you have your Fn key locked on toggle it. look for the key marked with Fn & press it again.

Go to control panel, click on accessibility options..in the keyboard tab, click on the settings buttons for sticky keys, filter keys and toggle keys and deselect the option to use shortcut..hopefully this will help you and other people that have had this problem.

try this go to start>>settings>>control panel>>accessibility options. Uncheck on the keyboard tab and uncheck everything under keyboard

I've run into this a lot myself and personally find it annoying more than useful. While typing, your punctuation keys suddenly switch to their french functions. By defaul, Vista assigns a keyboard shortcut fo changing input languages.

This shortcut is ctrl+shift - a very easy combination to press by mistake. To solve this problem, just press crtl+shift until you're back to english. You can change this shortcut or disable it all together.

Open the control panel then click "change keyboards or other input methods" under "clock, language and region". In the window that pops up, click "change keyboards..." then select the "advanced key settings" tab. This is where you can edit and disable language related shortcuts. To change one, click on the profile and then click "change key sequence". Under "switch keyboard layout", select "unassigned" to disable that shortcut.

Sounds like the CTRL key has a short and is pressing itself without your knowledge. Try replacing the keyboard.

Sounds like some of the keyboard settings have gotten changed. Begin by checking the System Parameters for Keyboard/Mice and verify that these are as follows:

Caps Lock = Caps Lock
Control Key = Control Key
Option Key = Option Key
Command = Command

If they are not, just press the RESTORE DEFAULTS setting and LOCK your Systems Parameter Page before closing it. Reboot your system and check keyboard operation.

Hope this helps,
