Hi there,

I’m pretty new to Codemirror6  
I’m trying to apply a transaction to my document which has multiple selections  
For each selection, I’d like to detect if the range’s from === the range’s to  
In that case I’d need to change the cursor position in the final document but always with this transaction

What I’m doing is

```auto
changes.push({from: ..., to: ..., insert: replacementText});

```

Then I have an Array of changes and I dispatch it by

```auto
.dispatch({changes: changes});

```

Which works fine  
But for some edge cases I need to update the selection in one go with the transaction  
My edge case is, that when there’s just the cursor (selection-start === selection-end) then I’d need the selection to “jump” further to the right in the final document for a given value

Does anybody have an example or an idea how that can be done?

I appreciate your answers  
Best wishes,  
Simon

Have you seen [`state.changeByRange`](https://codemirror.net/docs/ref/#state.EditorState.changeByRange)? That is written for pretty much this kind of use case.

Thank you @marijn , I managed to achieve what I wanted using `state.changeByRange` !

Thanks again,
