SAN FRANCISCO (AP) — New versions of Microsoft's word processing, spreadsheet and email programs will sport touch-based controls and emphasize Internet storage to reflect an industry-wide shift away from the company's strengths in desktop and laptop computers.

The new offerings appear designed to help Microsoft retain an important source of revenue as more people access documents from mobile devices. The new Office suite also reflects the fact that people tend to work from multiple computers — perhaps a desktop in the office, a laptop at home and a tablet computer on a train and a smartphone at the doctor's office.

Like an upcoming redesign of Microsoft's Windows operating system, the new Office will respond to touch as well as commands delivered on a computer keyboard or mouse.
