++++ ==== === set Performs set operations on selections with registers. This requires at least one register to contain selections (`"xZ` where `x` is the one-letter register name). * First argument is the register and operation ** For example `a-b` or `a&b` or `_?b` * Operations ** `&` - Set intersection ** `-`/`\\` - Set subtraction (order matters) ** `+` - Set union ** `?`/`=` - Set comparison (order matters) This will open a new scratch buffer comparing the selection counts and content * Registers ** Any register `a-z`/`A-Z` works ** `_` is treated as the current selection, and does not require you to manually set a register *** For example, `a-_` will return the set of selections in `a` that are not currently selected in the editor .Example [%collapsible] ==== `x` register (`"xZ`) content: ++++
