The collection of handled editor actions

This is primarily leveraged by the main editor processing loop for mapping user input sequences to handleable actions

Variants

Closes the application

Save

Writes the current buffer to a file

SaveAs(String)

Writes the current buffer to the file provided as an argument to the ‘:w’ command

Undo

Reverses the previous undoable action

UndoMultiple(Vec<Action>)

Reverses multiple previous undoable actions simultaneously

CenterView

Move the cursor up

MoveDown

Move the cursor down

MoveLeft

Move the cursor left

MoveRight

Move the cursor right

MoveTo(usize, usize)

Move to a specific (x, y) position in the buffer

MoveToTop

Move the cursor to the top of the buffer

MoveToBottom

Move the cursor to the bottom of the buffer

MoveToLineEnd

Move the cursor to the end of the current line

MoveToLineStart

Move the cursor to the beginning of the current line

MoveLineToViewCenter

Move the current line to the center of the view

MoveLineToViewBottom

Move the current line to the bottom of the view

MoveViewDownOneLine

Move the viewport down one line

MoveViewUpOneLine

Move the viewport up one line

MoveToBottomOfBuffer
