a better way to code this to fix a URL?

[Skaperen]

i understood post #8 until the output. the output at the end of #8 did not make sense to me.

Automatic correction of human input, leads to funny outcomes.

this is automatic correction of copy and paste errors that i often encounter. it doesn't start the highlight as quick as it should. i don't want to start all over. i just want it to work with the significant information to form the URL.
