Currently, OnCaretMove is the best place to do it.

Yes, sometimes OnCaretMove is generated several times on one caret movement,

but it's not a problem here.

As for actions, they update their state (Enabled and Checked properties)

periodicaly when the application is idle.

You can create your own actions: add TAction in the ActionManager, and

assign this code to its OnUpdate event. You do not need to use

RichViewActions for this.

It's simple, but less efficient than using OnCaretMove. But you can see that

though the ActionTest demo has many actions, they do not cause performance

problems.
