====== Color Grading shortcuts ======

List of available actions:
  - <key>'Left-click'</key> - page up/down of slider's position
  - <key>'Left-drag'</key> - drag slider's position
  - <key>'Right-click'</key> - reset slider to "neutral" position
  - <key>Shift</key>+<key>'Left-click'</key> or <key>Shift</key>+<key>'Left-drag'</key> - move 5 sliders at once
  - <key>Ctrl</key>+<key>'Left-click'</key> - set an "anchor" to be the current position of the slider, the anchor is removed once the <key>Ctrl</key> is released
    - [Holding <key>Ctrl</key>] <key>'Left-click'</key> - bring the slider to the same level as the "anchor"
    - [Holding <key>Ctrl</key>] <key>'Right-click'</key> - bring the slider to the same "resulting effect" as the "anchor"
    - [Holding <key>Ctrl</key>] <key>Alt</key>+<key>'Left-click'</key> - same as 5.b but applies to all the sliders, so it has an effect of aligning all the sliders in such a way that they produce the same "resulting" value on the device
  - <key>Ctrl+Left</key>, <key>Ctrl+Right</key>, or UI buttons <key>Left</key>/<key>Right</key> - shift the whole graph left/right by one position
  - Hold down <key>Alt</key> - show all the current curve's knees
  - <key>Alt</key>+<key>'Left-click'</key> on the slider knob itself (so not changing the position) - add a knee to the curve
  - <key>Alt</key>+<key>'Right-click'</key> - remove a knee from the curve
  - <key>Alt</key>+<key>'Left-drag'</key> - build a spline curve across the entire set of sliders
