Shift + Arrow doesn't work on Rider 2021.3.2

Hi.

I purchased Mac mini(M1) and install Rider 2021.3.2(for Apple Silicon).

In editor, press shift and any arrow keys(↑,↓,→ or ←) cause nothing.I hope to modify selection along caret moving by arrow key, as same as common text editor.

Is it possible by settings of Rider?

Thank you.
