Borland Sidekick was a personal information manager (PIM) launched by
American software company Borland in 1984 under Philippe Kahn's
leadership.
It was an early and popular terminate and stay resident program (TSR)
for MS-DOS which enabled computer users to activate the program using
a hot key combination (by default: Ctrl-Alt) while working in other
programs.
Although a text mode program, Sidekick's window-based interface echoed
that of the Apple Macintosh and anticipated the eventual look of
Microsoft Windows 2.0. It included a personal calendar, text editor
(with WordStar-like command interface), calculator, ASCII chart,
address book, and phone dialer. According to the prospectus for
Borland's initial public offering of stock to the public, Sidekick
sold more than 1 million copies in its first three years.
