You can set a default editor as well using the
editor<\/code> key in Kitty configuration file. The procedure is the same as changing shell.<\/div>\n<\/div>\n9. Notifying on command finish<\/h2>\n With Kitty, you can get a desktop notification when a long-running command finishes up.<\/p>\n
For this, uncomment the notify_on_cmd_finish<\/code> key and set its value to invisible<\/code> or unfocussed<\/code>.<\/p>\nI am going with invisible<\/code>, since, as per manual, it will:<\/p>\nOnly send a notification when the window both is unfocused and not visible to the user, for example, because it is in an inactive tab or its OS window is not currently active.<\/p><\/blockquote>\n
notify_on_cmd_finish invisible<\/code><\/pre>\nIf you are more into detail, set a time limit for the long command.<\/p>\n
I am going to set 20 seconds as the duration of a long command.<\/p>\n

The values for the keys in this section need to be fine tuned as needed for your satisfaction.<\/div>\n<\/div>\n
To enable it, first search for the key cursor_trail<\/code>. Uncomment it. I have set a value of 200 for it.<\/p>\nNow, set a value for cursor_trail_decay<\/code> and cursor_trail_start_threshold<\/code> as shown in the screenshot below.<\/p>\nCursor Trail Values<\/span><\/figcaption><\/figure>\nNow, reopen Kitty.

This is supported in Kitty version 0.38+. So, if you are using Ubuntu 24.04 or related system, the default package repo version of Kitty doesn’t support this.<\/div>\n<\/div>\n
For this, first open Kitty and run:<\/p>\n
kitten themes<\/code><\/pre>\nNow, from the list of dark theme, select a dark theme and press enter.<\/p>\n
