Add hotkey to Expand/Contract Y Axis on Charts

Please add “Shift + Mouse Scroll” to Expand/Contract the Y-Axis on the charts.

TSX currently has “Control + Mouse Scroll” to Expand/Contract the X-Axis. But there is no way to do this for the Y-Axis.

Yes, I know that scrolling on the Price Margin will adjust the Y-Axis, but it’s VERY slow.
If we have a hotkey for the X-Axis, we should get one for the Y-Axis. This will speed chart navigation exponentially.
