In Photoshop CC 2017, Adobe launched the new In-App-Search. You can activate the search with »Strg/Cmd-F«. Within the menu bar you will find the new function below: »Edit > Search«. You can search not only for Training and Adobe Stock, you can even more search for Tools and menu items.
I’m using this function for a few months and I’m using it plenty times. Back in the days without >>CMD-F<< each function and each filter had their own shortkey. For common used function like >>gaussian-blur<< or >>diffuse masking<< I still use the shortcuts, but more and more I use the search function. I just activate the “area” of Photoshop, because searching on Adobe Stock and the Tutorials would be slowing down the search progress.
You can also just search for some panels and display them. Furthermore, you can start Plug-ins from third-party providers with >>CMD-F<<.
The search function is used a total workflow accelerator, if you well-practised. Try it for a while, if you are not a completely keyboard-refusenik will you become quicker and more elegant in working with Photoshop.
