Multi-Carets

Introduction

Multi-carets feature allows to add many carets (text blinking cursors), using one of the methods:

Click on any position with Ctrl key pressed.
Click on any position ("beginning"), then click on another line ("ending") with Ctrl+Shift keys pressed: this will add multiple carets aligned in a column.
Make a several lines selection (stream or column), then use commands "Edit -- Multi-carets -- Carets from selection...".
Make a search with placing search marks, then use commands "Edit -- Multi-carets -- Carets from search marks...".

Most of important editor commands work synchroniously on all carets positions:

carets moving: Left/ Right/ Up/ Down/ Home/ End/ Ctrl+Left (move word left)/ Ctrl+Right (move word right).
text typing and deleting.
clipboard operations: Copy/ Cut/ Paste, they operate on all lines with carets.
special actions: delete word left/ delete word right/ delete line/ indent line/ unindent line/ delete to line start/ delete to line end.

To cancel multi-carets mode, just click without Ctrl pressed.
To remove a caret, just click it again with Ctrl pressed.
Lines with carets are marked on gutter with different color.
When several carets move to the same position, "duplicate" carets are discarded.
When only one caret is left, multi-carets mode is deactivated and "usual" caret appears.
These commands cancel multi-carets mode: Ctrl+A, Shift+Alt+arrows.
These commands ignore multi-carets mode and just scroll the view: PageUp, PageDown, Ctrl+Home, Ctrl+End.
Multi-carets feature can be disabled in the Options dialog.

Go to Options dialog.
First, you need to set option "Esc key" to "Do nothing".
Then, in the "Keys" tab, assign Esc key to one of the commands:
