Raj,
It definitely can be done.
Slider, if it is based on a variable, modifies the value of a variable. This can be done with buttons as well - "zoom out" runs a macro that adds 1 to a variable value, "zoom in" subtracts 1. Should be rather simple. Probably you want to set some limits for both changes, for example don't allow to go up above 15, and disable "zoom out" button conditionally, and don't allow to go below 2 by disabling "zoom in" button.

Hi Michael,

Thank you. But I have no experience with macros, so is it possible for you to provide me with the vb script.

just the idea of how to assign:

var_zoom=var_zoom + 1

This will work:


sub ZoomIn
 set z=ActiveDocument.Variables("var_zoom")
 z.SetContent z.GetContent.string-1, true
end sub
sub ZoomOut
 set z=ActiveDocument.Variables("var_zoom")
 z.SetContent z.GetContent.string+1, true
end sub

I don't consider here any conditions, just the basics.

Thanks a lot Michael.

One last thing, do you have a document (tutorial) on vb scripts, where it talks about 'getcontent.string','setcontent' etc.

Thanks & Regards
