Are you asking to change one entity to match the properties of another entity, including layer?
If so you can use the following string to create a custom keyboard macro to do basically this.
Code: Select allO^8#^S6^S7^S6^F1^$^32#^$^S0^S0^S0
//Entity nearest to cursor is changed to match the current settings
First you use "Identify" "Set all" (Alt-I) to make the entity properties your current settings then in my case I use Alt-O to set any given entity to those same settings.
In case you don't already have this set you should change Alt-I to be
So its a quick ALt-I on the first entity, then Alt-O on the second entity and they will now match.
