Yet again JetBrains managed to implement an "ungoogleable" feature.

Does anyone know what this "R with pencil" icon means? enter image description here

If you hover over the icon there is an explanation text: enter image description here

which means that this action will run Rename refactoring for the changed name of the symbol.

See IntelliJ IDEA 2020.1 EAP4: In-place Rename and Change Signature related blog post about it.

If there are no usages of this variable the Rename action (and icon) is dimmed and a bit different text is displayed (that nothing needs to be updated at this point): enter image description here

I don't know what the "R" exactly stands for, but it's used to reflect signature changes and so for refactoring methods.

I found the reason. This icon would offer me to "Rename Usages" after renaming the variable. I figure that where the R comes from.

However, in this case, there was no other usage for that variable, therefore the icon was just grey and dead (no tooltip or functionality).
