Oh, it works now.
So we need manually run this macro for using this function? Is there any other config settings that Emeditor can automatically detected this just like a normal link?
Thanks a lot, Yutaka.
Since highlighting tags can slower the overall speed of EmEditor and since most people do not need to highlight tags, it will not be turned on automatically. However, you can make it on always by selecting Customize on the Macros menu, select the above macro in the My Macros list, check Runs at Events, click Events button, and then click “File Opened” in the Select Events list.
