Just use a simple display by distance-zone command, in which you can put any distance you want, for example, waters within 5.5 Angstroms of protein:

show solvent & protein :<5.5

see the help on how to specify distance zones
<https://rbvi.ucsf.edu/chimerax/docs/user/commands/atomspec.html#zones>

The default initial display uses 3.6, as described in:
<https://rbvi.ucsf.edu/chimerax/docs/user/autostyle.html>

I hope this helps,

Then, viewing the MD system, I can observe an exchange of this water, which is great ! Would it be possible via some command to modify the number of the displayed water in the beginning of simulation e.g. showing more water observed in the proximity to protein (..but still not the whole water box !) ?
