Keyboard only causes Mac to "beep."
Suddenly typing only causes Mac to beep. The control, command, option, and tab keys work, but the numerals and digit is just cause a beep. Late 2009 iMac, Yosemity 10.2.2.

Hi kenka433,
You mention the numbers aren't typing but the modifier keys are working. Are you able to type the letters?
It sounds like there may be an Accessibility option set.
OS X Yosemite: If keys on your keyboard don’t work
If other keys don’t work
You may have accidentally set an option that changes how your keyboard operates.
Choose Apple menu > System Preferences, click Dictation & Speech, then click Text to Speech. If “Speak selected text when the key is pressed” is selected, deselect it or click Change Key to select another key.
Choose Apple menu > System Preferences, click Accessibility, then click Keyboard. Make sure Slow Keys is turned off. If Slow Keys is on, you must hold down a key longer than usual before it’s recognized.
Choose Apple menu > System Preferences, click Accessibility, then click Mouse & Trackpad. Make sure Mouse Keys is off. If Mouse Keys is on, pressing keys in the numeric keypad moves the pointer instead of entering numbers.
Choose Apple menu > System Preferences, click Keyboard, then click Input Sources. Select “Show Input menu in menu bar.” Open the Input menu, then make sure the correct keyboard layout is selected.
To see the keyboard layout, click Keyboard, then choose “Show Keyboard & Character Viewers in menu bar.”
Best regards,
Nubz
