In SciTE, can one view a file while temporarily disabling edit functions?

In SciTE, can one view a file while temporarily disabling edit functions? A lot of times I'll have files open for reading, but not for changes.  This could be a UDF, a system library include file, or one of my own stable files.  I just want to avoid making unintended changes accidentally.  I do this kind of thing all the time in Emacs with its "toggle-read-only" function.

Thanks in advance,
