TechWhirl (TECHWR-L) is a resource for technical writing and technical communications professionals of all experience levels and in all industries to share their experiences and acquire information.
For two decades, technical communicators have turned to TechWhirl to ask and answer questions about the always-changing world of technical communications, such as tools, skills, career paths, methodologies, and emerging industries. The TechWhirl Archives and magazine, created for, by and about technical writers, offer a wealth of knowledge to everyone with an interest in any aspect of technical communications.
I'm documenting a web-based program that uses graphic icons for various
functions. I have inserted screen shots in the list of instructions and my
question is this: should I repeat the graphic for a button (for example,
"Submit"), or is it enough just to write "Click the SUBMIT button", where SUBMIT
is in preordained font and weight (for example, Courier bold)? Will people
respond better to the repeated visual (they've just seen it in the screen shot),
or will they understand implicitly without repeating it?
