Your post was cut off because the 'smaller than' symbol was mis-interpreted by the forum software; check the forum FAQ for the appropriate functions. Here's your complete posting (edited for that problem):

I have been using Trados for many years and I do exactly the same.
(Well, almost - I use the 'smaller than' symbol, which is very handy on a Spanish keyboard, and I even have a macro to look for it later.)
Yes, the symbol does get included in the TM, but only temporarily - when you go back and solve the problem one way or the other, make sure you *open the segment* and remove the mark when you make your correction. When you close the segment, the old text will be overwritten in the TM.
You might like to look at Ando Tools (http://soukie.wz.cz)
which includes a slightly more refined method of doing essentially the same thing, as well as other utilities (and it's free).
