A method of scanning a document comprising:

• manually feeding said document through a slot in a housing without using mechanical document advancement mechanisms;
• capturing a sequence of image data as said document moves through said slot;
• generating navigation information representative of movement of said document through said slot;
• and
• forming an electronic image from said image data, including removing image distortion artifacts arising from said movement of said document through said slot, said removing image distortion artifacts being based upon said navigation information.

An integrated slot scanner and keyboard comprising:

• a keyboard housing with a slot configured for manually feeding a document through said slot, said slot extending completely through said housing and having first and second openings, said slot defining an interior surface of said housing;
• keys and associated electronics coupled to said housing;
• an image sensor positioned on said interior surface, said image sensor having an array of optoelectronic elements;
• first and second navigational sensors positioned on said interior surface, said navigational sensors being spaced apart, said navigational sensors having arrays of optoelectronic elements;
• and
• communication means for interfacing with a computer.
