- Favor Moves keys toward the previous/next keys. When multiple keys are selected, keys further from the next/previous key move more slowly. - Blend Moves keys toward the previous/next keys, like Favor. When multiple keys are selected, all keys move at the same speed. - Shift Moves keys toward the previous/next keys by moving them all together, they don't change relative to each other. - Linear Moves keys toward being on a line between the next/previous keys. - Average (curve) Moves keys toward the average of the next/previous keys on the same curve. - Average (frame) Moves keys toward the average of other selected keys on the same frame. - Average (all) Moves keys toward the average of the next/previous keys for all curves with selected keys. - Default Moves keys toward the default values. Usually this is 0, but some properties use other values. For example, scale uses 1. - Setup Moves keys toward the setup pose value. - Store Moves keys toward the stored curves. Use store to set the stored curves.

If you select multiple attachments in the view port and try to parent them to a bone using the hotkey, the slots will be duplicated but the attachments won't. The original slots will have a missing attachment so you cannot call it a complete duplication. If you filter the tree view by slots, clicking on the attachments in view port will select the associated slots. By using this filtering, you will be able to parent multiple slots to a bone without the awkward duplicating slot but not the attachment behavior.

You can customize Spine's hotkeys by updating the hotkey text file! Let's say we wanted to add a hotkey for the "bind" button for example... Go to Spine > Settings > Application tab > and open the hotkeys file. In the notepad window that pops up, ctrl+F to open the finder, type "bind" and it will take you to the correct spot. You can do something like "ctrl + alt + B" to add a hotkey (or whatever you want, just be sure to search the file first so you know there are no duplicates) Restart Spine and it should work when you have an image attachment selected!

Did you know you can attach slots to bones AND rename the bones while you make them, all at the same time?? 1) Select the Create tool 2) Then hold CTRL and select a slot in the viewport. It will outline the image in BLUE 3) Now release CTRL and then draw your bone. This will parent the slot to the bone, AND rename the bone to match the slot's name all at one time! This is a great way to speed up your rigging process. It was a game changer when I learned it because I no longer had to keep renaming every single bone and then adding each image to those bones one by one.
