Fish is known as a shell that works out of the box, scoring points with autosuggestions, syntax highlighting and helpful completions.<\/p>\n\n<h3 class=\"wp-block-heading\">Less friction in interactive use<\/h3>\n\n<p class=\"wp-block-paragraph\">In the KDE terminal Konsole, the kitty keyboard protocol had been breaking scrolling; Fish 4.9.0 disables the protocol there by default, though it can be re-enabled via a feature flag. Tab completion is now noticeably faster in directories with slow symlinks. On terminals such as kitty, the Space and Shift+Space keys can also be mapped independently.<\/p><div id=\"netgu-352870256\" class=\"netgu-content netgu-entity-placement\"><aside class=\"deals-top
