A problem in Notepad++
I open four tab in Notepad++ and use ctrl+alt+R. In all tabs, the text goes to the right while I used it for just a tab.
welcome to the notepad++ community, @Ramin-Parsa
this is the default behaviour and has always been that way.
when you switch from ltr to rtl, notepad++ will switch to right to left text editing for all tabs.
