Spent 15 minutes trying to read a PDF (a building code). No + - zoom choices anywhere.

finally read here "hover at the bottom" to make the zoom controls appear. they did, it worked.

But what space does this silly mechanism save? None. It seems there only so some developer can display his tricks. Maybe this is an option for the author; if so it should be strongly discouraged.

I don't recall ever having to look so hard to do something so simple and reasonable. On a par with Windows hiding arrows at either end of a scroll bar, so the user has to sort of feel in the dark for them - to absolutely no advantage.

Hover to the bottom of the page to make zoom and other controls visible. There you get an option to "Move page controls to toolbar". Click on it, there you go!

Thanks vm Anonymus, it was a simple as that!

This is really COUNTER productive!
If only the keyboard shortcuts were working. I mean with a belgian keyboard (i guess that's the reason), zoom out is not ctrl+minus BUT ctrl+8!!!

One could go on the toolbar and right click and select > reset toolbar and the option returns back.

The controls are still hidden, you have to click the Zoom + icon before you can then click to zoom in and out. This is awful to use and causes frustration multiple times per document. How can you make the +/- controls stay in the toolbar, so you can click them directly?

Hello,
You can also press CTRL + Mousewheel for zooming.
But you have to click the document first for that it's active. It's weird because by default it should work just by hovering the document (in inactive documents).
I'm also a developer and i also think that some one does not research the default functionalities enough before implementing the zoom function in Adobe.

I'm up-to-date and if i got it right, you can't dectivate the dynamic zoom without restarting Adobe.

I will see the hole page and spend hours to find the button for it. Adobe developer are idiots.

one of the most basic functions removed! how dumb!

I was searching for the answer to this question as well, which is how I found this question here. I'm used to those controls being at the top, like past Reader versions. But they're auto hidden at the bottom of the page!! You need to hover at the bottom of the page to see the bar. SMH.Hope this helps.

Me too, one of the most useful tools, idiocy to remove it.

Hi all,
For compensate the missing Zoom In (+) and Zoom Out (-) buttons, I activated the button "dinamic zoom" and once selected, you can zoom-in/zoom out with the mouse wheel.

As an engineer, I don't think the engineers decided to do this. Engineers like to add features, and redesign the code, they don't take features away. I'm guessing it's marketing/product managers who seem to be in love with a "simple clean look". (I admit adding features and redesign the code are not always good things--it can break existing features. THAT is engineers fault.)

Just found out -again- that sometimes it's the simplest thing. Check first to be sure your ai page isn't on the (half) minimize screen mode. That tool only shows up if it's on full screen.

View > Show/Hide > Page Controls > Show Page Controls.

If this adds it as a pop out, click the button on the far right of the pop out tool bar and add it to your controls at the top.

Given that this has been "under review" since January 8 2019, it is clear that Adobe do not see meeting their users needs on this as a high priority.

Wow, I couldn't have said it better. Thank you all for help getting these back. I HATE when programmers mess with great things thinking no one is using them. It is obvious that everyone does.

Solved this. I use Preview on Mac. Works fine. Adobe seem determined to make what was a good program unusable, and charge an annual fee for the privilege.

This is really messed up. For the second time in two years I had to hunt down the + and - buttons by looking through various threads like this one until I figured out how to fix it (see answer below). Just wasted a good 30 minutes of my work day, again. Why in the world, Adobe, do you keep moving those buttons and keep messing around with them? It should not be this hard. Please, PLEASE make them easy to find and then leave them alone.
I shouldn't have to waste so much time hunting down a function that is essential to reading thousands of PDF documents a month. I don't want to click 30 different buttons to zoom in on the page I'm currently reading. Sheesh.
