Find the HackMaster home page and get reading. HackMaster is a loader/manager that makes sure that different system extensions are loaded and unloaded without destabilising the OS and it's got some good documentation on doing what you want for Palm OS 3 and 4.
Under Palm OS 5 the concept of notifications and notification handler became the preferred way to do things (I think notifications were introduced in Palm OS 4 but it became necessary to use them in 5 because PalmSource started tightening up the OS in order to support ARM processors so a lot of the old hack techniques stopped working). With notifications your app starts up just long enough to lock a segment of code, register for a few notifications and point the OS at that code segment and then exit again, leaving the locked code segment in place). When I built one I followed a step-by-step guide that might be on Ben's site - it was a while ago so I'm not sure. There's a notification for the user requesting the popup keyboard, which I guess is what you'd be interested in responding to. Sorry to be a bit vague, but I last did this about a year ago.
