Emacs incremental search (isearch) offers a wide range of features, but many of them are difficult to discover and remember. Additionally, the default keybindings for these features are not user-friendly. However, with the introduction of the Transient package to Emacs 29.1, there is now a workaround. By using the Transient menu in isearch mode, users can access a set of isearch-specific commands. These commands include edit commands, replace commands (if the buffer is not read-only), toggle commands, and miscellaneous commands. This menu makes it easier to use isearch for routine needs such as query-replace and query-replace-regexp. The implementation of this workflow is shown in the source code provided. Overall, Transient has made these isearch features more usable and discoverable. With the recent inclusion of Transient in Emacs 29.1, there is potential for users to explore and improve their Emacs workflows using this new capability.
