Understanding pages and button grids in TD Snap

What you NEED to understand about how TD Snap pages and button grids work
“Block flow” is TD Snap’s default approach to repositioning buttons when transitioning between grid sizes. TD Snap will attempt to preserve the position of the buttons in the visible columns. Buttons in columns that are no longer visible will be moved to the to the first available empty rows. Depending on the number of buttons on the page, this might be on the next grid screens down, perhaps multiple screens down.
TD Snap will stop using the “block flow” approach, at least for the current grid size, once you reposition a button in the grid. TD Snap assumes made the positional change for a reason and you want to preserve that, so it creates a “saved state” for the current grid size. If you then transition to another grid without a “saved state,” TD Snap will “block flow” the buttons accordingly. If you are transitioning to a grid size where you previously repositioned a button, TD Snap will restore the “saved state” for that grid size and it will ignore any positional change made in the previous grid size.
“Saved States” are helpful to ensures that, across all grid sizes, button content maintains a consistent structured, i.e. function/navigation buttons are always in the same position, buttons grouped by part of speech or spoken intent. Note, there are two separate “saved states” for each grid size, one for when Navigation Buttons are not enabled (Touch access method), and the other when they are enabled (all other access methods). (See Navigation buttons will displace buttons on your pages.)
Navigation buttons will displace buttons on your pages
In TD Snap, up and down Navigation Button will be added in the upper and lower right corners of every page as needed if the access method is set to anything other than Touch. The navigation buttons allow you to scroll between grid screens on the current page. The button(s) that were in the positions now occupied by the Navigation Button(s) will be relocated. If Touch access is selected again, the buttons will return to the original positions.If you don’t want navigation buttons to appear on a specific page, you will need to hide all the buttons on the screens below the first screen.
