A macro to mirror the movement of the cursor

[ACA]

I am somewhat familiar with macros for EXCEL, but not for WORD.

I often translate documents; I have the original text in one window of WORD while typing my translation on a second window.

I’d like to assemble a macro that will somehow mark a spot (a word, for instance) on the first window and then make that mark move forward mirroring the movement of the cursor on my other window as I type.
That would make it easier for me to see the spot I have reached, each time I turn from looking at the typing window to looking at the original.

If this can be done, please give me some hints from which I can start.
Thanks in advance for any help.
