numbers 3 8 11 13 are great I didn't know about them although I have been using macos for near 20 years. Guys who build software should make it more clear for people about these hidden features they worked to build them in their apps/os .
 
A couple of tricks I learned from imaging big Mac labs...
  • Press <Ctrl>, <Eject>,<Return> to shut down
  • Press <Ctrl>, <Eject>, <r> to reboot
  • To eject an external drive with multiple volumes/partitions:
    • Select it and press <Cmd>E (as usual)
    • When you see the dialog asking if you want to eject all volumes, press <Cmd>E again
  • If you have View Path selected as a Finder option, you can click on any folder in the path to go there
Enjoy!

“If you have View Path selected as a Finder option, you can click on any folder in the path to go there”

Same for Finder BTW. Not sure why Path Bar isn’t turned on by default.
 
Is this right? I mean, it doesn't seem to work on .txt, .rtf, .rtfd or .html files, and it doesn't explain how you would go about saving the downloaded webpage to convert it. Would you select all the files in the Files folder at once and convert them to a single PDF or what?

All of these file types could be printed to PDF, so it's no big deal, but I'm just curious if I'm missing something here.

It is true it works for images and combining multiple PDFs.
Yes, preview is mainly for images and the conversion to PDF is for that. All of these text file formats are more complex and there are too many options to make a conversion quite so easy, so I guess they just assume you will open them in their respective editors and print to PDF to do the conversion or save to PDF when the apps have that as an option. In either case it is pretty easy to generate PDFs from those kinds of files.
 
Jumping to the enclosing folder is the dumbest feature because you cannot determine where that folder resides.
That is a very valuable feature. When you find a file via search, jump to folder takes you to that location where you can see the folder, see the associated files and take action on the file you found or the other files. At the very least, it shows you where that folder is.

It may be that you have no need for this feature and / or you work differently but people do file management in different ways either because of different use cases or because of their preferences for how to work. Don’t call something dumb just because you have no idea how it is used.
 
Show your Path Bar:

In Finder -> View -> Show Path Bar

When you make the jump in Spotlight, you will see the path to the enclosing folder.
Also, if you right-click on the Folder name in the toolbar at the top of the window, it will show you the full path to that folder and you can navigate up the tree.
 
Closing all windows of an App (e.g. Finder) is much faster with CMD-option-W... just in my opinion since that is without mouse interaction.

One VERY important shortcut for me at least:

Shift-Ctrl-CMD-4 - screenshot - but it will not save the file, it copies the screenshot into your clipboard for pasting instead of creating a file that you later might have to delete just because you wanted to make a quick screencap for a PowerPoint or whatever.
 
You can change the default screenshot image format from PNG to JPEG which will save a lot of space and the image looks the same.

Another good one:
You can convert HEIC images to JPEG (maybe you airdropped a photo to your Mac and want to send it as JPEG by email). You can convert one or several directly in Finder. Just right click on the HEIC image and select the option “convert to JPEG” as in the same fashion as when convert a file to PDF.

would be helpful if it could do format conversion of any file to any file
 
Most of the keyboard shortcuts can be used on an iPad with Smart Keyboard attached.

Point 12-14 all work. Point 15 (shift + Cmd + 4) takes a screenshot and automatically displays the screenshot with edit/crop options, but pressing the option key or the spacebar whilst cropping is not applicable.
 
Always find something new - didn't know about the ⌘+R shortcut for Spotlight. Thanks!
I always use Spotlight completely by keyboard (no mouse clicks involved)!
  • ⌘+Spacebar, to quickly open or close Spotlight
  • Cursor-up and Cursor-down to scroll through
  • Option-key on a selected file to view the path where it may reside
  • ⌘+Enter, to open the enclosing folder - does the same thing as ⌘+R, but is far easier to reach on the keyboard

If you hold down Option on the selected file in Spotlight, it shows you the complete path for this file. So you will know beforehand where this jump takes you - if this is important for you.

A couple of tricks I learned from imaging big Mac labs...
  • Press <Ctrl>, <Eject>,<Return> to shut down
  • Press <Ctrl>, <Eject>, <r> to reboot

Because of <Eject> I assume this no longer works on Macs without optical drives?
I’d love to have a keyboard combination to shut down/reboot :(
 
If you only need a few pages from a large .pdf file you can create a new .pdf of just those pages using the print menu.
Select the print command then use the 'Pages' command and set it for the range of pages you want.
Then use the PDF dialogue button bottom right.
BUT if you chose to open it in 'Preview' in that PDF menu and then use the 'Export' command in Preview and then go to the second line 'quartz filter' then 'Reduce file size' you can get a .pdf of just the pages you want but with a much reduced file size. It can take it from over 2MB to about 400KB which is great for sending by email or when uploading documents
Always open it and check it first though as sometimes it compresses it too much and the quality isn't good enough.

You can also use Spotlight search as a calculator, currency converter, height and weight calculator, temperature converter, speed converter etc.

I find it super useful, also works on iOS and iPadOS.
Also if you use the calculator app there is a convert menu there.
The best workflow is type in the number you want to convert first then go to the Convert menu, set up the parameters and then press convert. It's very extensive and even has up to date currency conversion.

Just a reminder:
Ctrl+A= select all
Ctrl+C= copy
Ctrl+V=paste
Ctrl+X=cut
Ctrl+Z= undo previous command
 
How to prevent audio balance drift when changing audio volume? (Third-party headphones, mine are Sony WH-1000XM4)

It's true JPEG will create smaller files, but PNG images are visually superior in some situations - the image does not look the same. PNG is better on text, and supports transparencies.
Are all these things in the macOS documentation? If not, they should be.
Ha. When OSX came out, I bought a book called The Missing Manual. It was like 700 pages. I can't imagine how many pages a Monterey Missing Manual would be. They were great books, but they no longer make them. I agree with you though - all this stuff should be included through the Help screens.
 
I'm not quite understanding which files can convert to PDF - and which can't.

I have Quick Actions set up and see Create PDF if I select a .png or .jpeg. But not if the file is an RTF or docx.

How do I extend the range of file types which can be converted to PDF?

And, if I can convert Word documents, is it possible for them to include ToC links?
I never create pdfs that way. In each app, you can usually export to pdf, or alternately print, and select save to pdf
