@Valery_Kondakoff there is dedicated and already implemented request for that.
Related feature request / one possible solution: File Explorer: Navigation Hotkeys
(I expect that request to be merged here.)
Someone might prefer to keep content of active pane preserved while navigating File explorer by keyboard. In that case the solution would be to display Pop-up preview of focused file while the File explorer is “active” when we press one of recognized navigation keys.
Pressing Enter would then open it in the pane active active before activating File explorer (unless that pane is “pinned”). Or Ctrl+Enter in new pane as is the current behavior for opening links. At that point the pop-up preview would disappear and it would also when we “deactivate” the File explorer by activating something else (standard pane, search pane, …).
