Change the Keyboard Preferences
These settings allow you to configure the repeat rate, blink rate and repeat delay of your keyboard.
Open your registry and find or create the key below.
To set the keyboard delay create a new DWORD value, or modify the existing value, called "KeyboardDelay" and set it to either 1, 2, 3 or 4 where 0 = ¼ second , 1 = ¾ second, 2 = 1¼ seconds, 3 = 2 second delay.
To change the number of keys inserted during a repeat operation create a new DWORD value, or modify the existing value, called "KeyboardSpeed" and set it a number between 0 and 31 with 31 being the fastest repeat.
Settings:
User Key: [HKEY_CURRENT_USER\Control Panel\Keyboard]
Name: KeyboardDelay, KeyboardSpeed, CursorBlinkRate
Type: REG_SZ (String Value)
Note: People who experience seizures in response to flashing lights or patterns may have problems with the blink rate of the insertion point if it is set at a frequency above 3 to 5 times per second.
