Keyboard shortcut to decrease playback speed on YouTube doesn't work with Chrome (on german keyboard layout?)

Solution 1:

I have exactly the same problem and found a solution:

1. Go to Preferences > Keyboards > Input Sources (Systemeinstellungen > Tastatur > Eingabequellen) and add another keyboard layout, e.g. "English".
2. Activate the keyboard input in the menu bar (checkbox below called "Eingabequellen in der Menüleiste anzeigen" in German).
3. Now you can switch the keyboard layout to English and then Shift-press "," or "." on YouTube in order to slow down or speed up.

Background information:

On US/UK keyboards the < and > symbols are on two different physical keys next to the m key and both of them have to be shift-pressed.

On a German keyboard the < and > symbols are both on the same physical(!) key (right next to the left shift key).

Probably this is the cause problem, so the < does not get detected, because YouTube thinks both functions (speed up, speed down) need the shift qualifier pressed simultaneously.

Solution 2:

I have the same problem.

My computer is an iMac (mid 2017) with Spanish-ISO keyboard and Mojave. I can't find any working keyboard shortcut to reduce the playing speed in Youtube.

I've tried with different browsers (Safari, Chrome, Opera and Edge) with the same bad result in all of them.

Curiously, Firefox and Tor browsers seem to work well. With Firefox I can use the combination Shift+ and Shift+ without problems to change the playing speed. With Tor Browser, just using the < key and the combination Shift+< (>) works.

I've also tried in a virtual machine with Windows 10 in the same computer and keyboard without any issues. So, definitely, there's something wrong between Youtube, macOS and some browsers.

Changing the keyboard language in preferences and choosing English works correctly, but of course is not the ideal solution. I would like to find a better solution to do this with Safari and continue using the Spanish-ISO configuration of the keyboard.
