In my innocence I thought cLive ;-)'s response was odd.

But looking at the data and reflecting on the term "keylogger", I am now ready to ask also: "What color is your hat?"

Beyond that, there is a lot more involved in this to accomplish what you now propose. Not the least of it is that parsing this data will require that the parsing script have a copy of the document being worked on since, from the snippet given above, it seems clear that the typist being logged is moving forward through a pre-existing document.

Let me risk going a step further and suggest that this task is effectively beyond the range of any reasonable expenditure of effort. You list <Up>, <Down, <PgUp>, and <PgDown> as keys that will be in the keylogger data. Knowing where these keystrokes will take the curser would require a lot of information and a lot of calculations on margins, font size, variable width character metrics, etc.

Good luck.
