Hotkeys for Drawing

I see how to configure hotkeys in the preferences. I set up hotkeys for drawing on the chart, but I can’t figure out how to activate them. I have a key to draw a line, for example but when I hit the key, then click to draw, I get nothing. I tried every combination of key-click, click-hold-key, key-click-drag. Nothing.

You have to turn on hotkeys on the chart. It’s the H icon in the top right of the chart near the fullscreen/close icons.

That was the trick. Thank you!
