+MoreGallery 1.6 introduced batch actions for activating (showing), deactivating (hiding) and removing images in a gallery.
+
+Start by ticking the checkbox shown in the top right of images. This can also be done [from the keyboard](Accessibility) by focusing on the image and hitting `space`. When at least one image is selected, the bulk toolbar will show up at the bottom of your screen which can be focused with `alt`+`b`.
+
+The bulk toolbar looks like this:
+
+![Bulk Toolbar](images/bulk-toolbar.jpg)
+
+From left to right, these are the provided functions in the toolbar.
+
+- Select all images
+- Deselect all images (which also hides the bulk toolbar)
+- Mark all selected images as active/visible
+- Mark all selected images as inactive/hidden
+- Remove all selected images
+
+Keyboard users can tab through these options and execute them with `space`.
+
+Batch actions are processed server-side, followed by an automatic refresh of the gallery.

+In 1.6 we've made MoreGallery more accessible for keyboard usage. It should work intuitively by `tab`bing around, along with the following shortcuts and keyboard behaviours.
+
+To jump the focus to specific features,use:
+
+- `alt`+`t` to jump focus to the **t**oolbar
+- `alt`+`g` to jump focus to the first image in the **g**allery
+- `alt`+`b` to jump focus to the **b**ulk toolbar, only if it's visible
+
+When focus is on an image (either from tabbing or from `alt`+`g`):
+
+- Use `left` and `right` keys to navigate through images like you would with `tab` and `shift`+`tab`. 
+- Use the `space` key when on an image to select it for [batch editing](Batch_Editing).
+- Use the `down` key when on an image to go into the image actions toolbar. While there, `left` and `right` will let you jump between the actions and `space` will trigger them. Use the `up` key to place the focus on the image again. 
+
+When modal windows are opened, it automatically focuses on the first focusable element in that modal. As the fields autosave, just `tab` out of a field to let it blur and save. Use `enter` to select a tag from the dropdown, or to create a new one based on what you typed. 
+
+Closing modals is done with `esc` or by focusing on the `X` button and triggering with `space`. After closing the modal, focus goes back to what was last focused.
