Methods, apparatuses, systems, and media for generating characters for electronic devices using condensed keyboards are disclosed. Embodiments comprise a method of manipulating a set of keys adapted to be manipulated using fingers of a left hand and a right hand of a user, each of the keys capable of generating multiple characters. A variation of the method includes using one or more keys adapted to be used by thumbs of the user to generate other characters and/or control characters. Other embodiments comprise keyboards, apparatuses, and portable electronic devices that comprise two sets of keys for manipulation and desired character generation. The keyboards generally have four or more keys for each hand, and the keyboards may be located on the back and/or sides of portable the systems.

What is claimed is: 1. A method to generate signals to select characters for a portable electronic device using a condensed keyboard, the method comprising: directing movements of keys of a first set of keys and a second set of keys to selected positions in response to pressure on the keys, wherein the directing movements can comprise directing one or more of the keys into the selected positions of three or more actuation positions available for each of the keys located on one side of the portable electronic device, the one side arranged to be facing away from a user when the user is to operate the condensed keyboard, wherein the directed movements associated with the first set of keys are adapted to substantially mimic finger movements between keys by a right hand of the user and the directed movements associated with the second set of keys are adapted to substantially mimic finger movements between keys by a left hand of the user; and generating unique signals in response to actuation of each of the keys at the selected positions. 2. The method of claim 1, further comprising generating a thumb signal in response to actuation of a thumb key, wherein the thumb key is located on a front side of the portable electronic device, the front side arranged to be facing the user when the user operates the condensed keyboard. 3. The method of claim 2, wherein generating a thumb signal comprises generating a signal to select a "space" character. 4. The method of claim 1, further comprising altering one or more of the unique signals in response to actuation of a thumb key. 5. The method of claim 1, further comprising displaying visual cues on a display screen of the portable electronic device to help the user determine which keys to actuate to select desired characters. 6. The method of claim 1, further comprising returning at least one key of the first set of keys to a home position after depressing the at least one key.
