Is there any way to have comment templates whenever we are typing comments?

We already have a comment template thread but oftentimes it takes a long time to open meta, go to the question, wait for the page to load, scroll down to the correct comment and copy it, especially if one's internet is slow. Is there any way we could have an opt-in method for a side-panel to open up when typing a comment with the common comment templates straight from that answer. If not, could we have a user-script to do the same job?

• If somebody has enough time to try it out, perhaps this userscript is worth checking out: QuickComment: comment shortcuts to cut down on tedium. (And it's possible that you might find some other similar tools on Stack Apps.) Jun 8 '19 at 16:04

I have always used AutoReviewComments with great pleasure. It sounds like it would exactly fit your wishes.

It is completely configurable using a text editor, using which you can easily include your favourites from the list of comment templates.

As an aside, to save you time copy-pasting in general, you could look into using a clipboard history like ClipX. It has become an indispensable "quality of life" tool for me.

If you're on a Mac, text replacement shortcuts are a built-in feature. Its less capable than the other options, but requires no installation and should Just Work in every browser (in fact, system-wide, which might be too much...)

You can find this option by opening System Preferences > Keyboard, and then the Text submenu. You should see this window (or something similar if you're on a newer OS):

The +/- in the bottom left lets you add/delete items in the list. For instance, typing msehow(apparently its not case-sensitive) and hitting space turns it into the following text that I just made up:
