P: Save for Web, unable to use short cuts in save dialog (Copy/Cut/Paste) file name

I have the same Problem:

OSX 10.15.5
MacBook Pro (16-inch, 2019)
2.4 GHz 8-Core Intel Core i9
64 GB 2667 MHz DDR4
AMD Radeon Pro 5500M 8 GB

Hi,

Running PS 21.0.3 and I've noticed an annoying glitch (was also in the previous version) and now it's just too time-consuming so I need to ask what am I doing wrong. But this was working fine not so long versions ago.

If I use cmd + shift + s I can paste (cmd + v) any text I want to use for a file name. Text/name from email, web, word...

If I use cmd + opt + shift + s copy-paste (cmd + v) is not working at all. This is insane 'coz working with mouse Right click + paste is... huge step back.

And another annoying thing.
When I want to save file for the first time a generic, system, automatic,... name is generated and is highlighted together with .jpg (for example). If I just use a copy-paste text for name and hit save the extension .jpg is gone.
So much working with Right mouse click that it's insane!

Restart, reset PS settings,... not working or helping. Just more lost time to set up everything back as I wanted to have.

THANK U!!!

Recently noticed that when doing a Save for Web (Legacy) the file name text field is neither copyable or pasteable. By contrast, a Save as... will allow me to copy and/or past the file name. Not sure if this is tied in with the other naming issues like the file extension being highlighted but weird that it is locked for some reason.

I'm having this problem in the latest version of Photoshop and Illustrator CC on a brand new, up-to-date Macbook Pro.

It was acknowledged by someone at Adobe in the earlier thread, but it was moved into this extremely old one that's been collecting dust ever since. If everyone who has me too'ed the issue can create a new issue instead, perhaps Adobe would see that it is a big issue for a lot of users. 

Hey Guys, does anyone at Adobe read these comments? It's been 6 years since the first one and you still can not copy and paste a file name. That seems like a pretty simple and "take for granted" functionality that most users would just expect. Is there a long term plan here? Can you give us a year count down on when this might be addressed? 6 years, damn.  

Howdy Denny,
If you're referring to Save for Web on Mac, there is a known problem on Catalina with shortcuts, but otherwise, this should work.  Are you running Catalina?
Thanks,
David

When attempting to copy a layer name using 'command + c' (on Mac) then Export As (Legacy) and 'command = v' to paste the name, nothing happens. 
I tried using the menu and that does not work, either.
However, using the mouse right click pop-up menu does work. 

Following update to Catalina and Photoshop 2020, 'Save for Web (Legacy)' does not recognise standard keyboard shortcuts cmd+c (for copy), cmd+v (for paste) or cmd+x (for cut) in the filename field. 'Edit' flashes in the menu bar when the combinations are pressed, but they have no effect. Right-clicking does bring up the cut/copy/paste options, which do work. But for accessibility we need the keyboard shortcuts to work as they always have in the past. The keyboard shortcuts work in all other apps, and they work elsewhere in Photoshop.

Please fix the save as dialog box to work with Catalina. This issue is a serious workflow buster.
