I replaced the last curly quote with straight quote and it worked!

C:\Windows\System32\cmd.exe /K "cd /d C:\Users\admin“

Wow! That hits the bull's eye!
Needless to say this is going to be one of the most frequently used shortcuts during my PC work. So often do we require to alternate between a browser and a word doc or a browser and a spreadsheet.
Thank you.

I pasted the above code in Fastkeys short cut Ctrl+space.

I opened the browser and then I opened the notepad. I pressed the above short cut (Ctrl+space) and the notepad window got minimized. I again pressed the same short cut, but this time the notepad didn't return to its original position.

I use this script to minimize the topmost open window with the shortcut ctrl+space: WinMinimize, A Is it possible to maximize it again using the same command? I mean : ctrl+space - 1st instance - minimize the topmost open window and ctrl+space - 2nd instance - maximize the same window

It is still opening this way only:

The system cannnot find the path specified.
C:\Program Files (x86)\FastKeys>

I already tried that. The cmd opens like this: C:\Program Files (x86)\FastKeys>

I want it to open this way: C:\Users\admin>
This is how it opens regularly.

Want to assign a command to open Command Prompt using shortcut Win+C.
Can anyone help me with the script?

In Windows, one has to go this way to open the sound equalizer: Sound > Speakers > Properties > Enhancement > Equalizer and then click those 3 dots in the corner. Is there any quick way to open it?

Any short cut to minimize the topmost open window?

Under the settings, Run Fastkeys on Startup is enabled. Previously, it would open by itself but since a few days, I have noticed that Fastkeys doesn't start with the PC. What could be the problem? In the task manager, too, the startup is enabled.
