I did a quick Google Search for "create bold entries with Instant Text" and found this:
How do I create a bold heading?
In the Add window click on Command/Record keyboard shortcut, then press Ctrl+B and click OK. Add the Ctrl+B command before and after each entry item you want bolded. Once you have added the first {Ctrl B} you can copy {Ctrl B} and paste it wherever needed in the entry.
