Describe the bug

In interactive steps (especially when cursor moves, like paste) the entry is refreshed many times.
We should try to reduce any refreshes that occur in quick succession in case they result in multiple frame draws.

How about to add a flag to disable the refresh? We can set that flag before we call some functions, then disable the flag after the procedure we need. After that, we can do the refresh manually.
All we need to do is to add the code to check the refresh flag in the Refresh() and update the flag where we need.

I think it is better to rework all the internal methods to not refresh and then have the exported methods refresh (or something along those lines). Some kind of refactoring basically. Having a flag in the struct to disable a specific function seems like a bad practice in my opinion.
