There is a "Fill and Stroke:" dialog where you can change color in HLS model and see the result immediately.
There are also color gestures which work in HLS color model that provide real-time feedback.
For what effects do you want hotkeys? If you mean the ones like "Effects - Color - Less saturation", you can easily assign them yourself the way you like it. You only need to run 'inkscape --verb-list' to get a list of all actions to which you can map a hotkey. Then you edit keys.xml by adding new hotkeys.
