A TSR is a Terminate and Stay Resident program. Such a program stays in the memory even after the user exits it, so that it can be recalled by hitting a custom key(s). To write TSRs, you need an understanding of how to interact with hardware on your computer through pointers. It needs a good knowledge of C, and there are some good books specifically on TSRs. But those are not used much anymore, since the advent of windows :).
