end

.change_word_right_end(text, count = text.prefix_count) ⇒ Object

word_right_end

goes to the last character, that is, the insert mark is

between the second to last and last character. This means that the range to delete is off by one, account for it here.

.delete_motion(text, motion, count = text.prefix_count) ⇒ Object

Given a motion, this method will execute a virtual movement with the count argument and [delete] the corresponding indices.

Parameters:

  • motion (Symbol String) —

    name of a method acceptable for [virtual_movement]

  • count (#to_i) (defaults to: text.prefix_count)
