<h3>Flexible Navigation & Instant Replace</h3>
This tool provides a seamless way to navigate and edit your content with precision:
<ol>
<li>
Precision Navigation (Keyboard & Buttons) 
Effortlessly cycle through matches using the “Next” (Enter) and “Previous” (Shift + Enter) keys. You can also use the “Current” (◎) and UI buttons to jump directly to the selection in the editor.
</li>
<li>
Smart “Click-to-Select” 
Click any highlighted match in the editor to instantly set it as your current position. This synchronizes the sidebar counter and focus without jumping the screen.
</li>
<li>
Instant “Double-Click” Replace 
For a faster workflow, you can double-click any highlighted text directly within the editor to replace it instantly.
</li>
<li>
Auto-populate from Selection 
Enable “Auto-populate from selection” in the sidebar to automatically update the search field whenever you highlight text in the editor. This eliminates the need for copy-pasting.
</li>
</ol>
Additional Notes (Performance & Scope)
Dynamic Highlighting Scope: 
To maintain high performance, the editor highlights the 300 matches nearest to your current position (150 before and 150 after). As you move through the document, this highlight window shifts automatically.
Unlimited “Replace All”: 
The “Replace All” function is not affected by the highlight limit. It will accurately replace every single match throughout the entire document, regardless of whether it is currently highlighted in the editor.

HTML Editor Syntax Highlighter

And what's really neat, is that there is no WP Admin page, all settings are performed while editing. This is a perfect job. I have only used the classic editor (still waiting until Gutenberg is more mature). A previous reviewer wrote that text added in the Text tab is lost when switching to Visual - I have not seen this happen. I'm very happy :)

Superb, more options than I imagined

HESH is built on top of Code Mirror which is first class code. The implementation is somewhat eclectic including a settings button in the front end which allows the user to really play with editor settings. Easy access to the settings is convenient at first and then a bit of a distraction.

HESH even highlights WordPress shortcodes [shortcode] syntax.

What HESH doesn't have is Markdown syntax highlighting in the posts/pages plain text editor but the WordPress shortcodes and HTML highlighting helps make up for it.

What is buggy are the settings on iPhone (iOS 13.5) where the settings buttons more or less don't work and the settings can't be closed. If you don't touch the settings though, HESH provides a better plain text editor than WordPress default (which can be very finicky to accept text entry). It remains easier to edit on iOS with HESH installed than without so no downnmarks here.

All in all a great plugin, a bit overwhelmed right now with legacy support for WordPress 4.9 editor, Classic Editor, Code view, plain text editor, Gutenberg and the sixteen different kinds of blocks which might need syntax highlighting. I can't blame the plugin authors for not being on top of all editors all the time now in the current Gutenberg-induced editor hell.

Very, very grateful for their hard work and looking forward to HESH v3.

Works, even on iOS/mobile
