JetBrains Rider supports multiple carets. The majority of the editor actions, such as keyboard navigation or text insertion and deletion, apply to each caret. Live templates and auto-completion are supported as well.
It is possible to add or delete carets; at least one caret always exists in an editor tab.
The most recently added caret is considered primary. Highlighting of an editor line at caret applies to the primary caret only.
Placement and behavior of the carets depend on:
Enabled or disabled column selection mode .
Enabled or disabled placement of caret after the end of line.
Refer to the section Selecting Text in the Editor for additional information.
