Performing Keyword Search with SPRITEs

In addition to navigating tables by leveraging their spatial structures, SPRITEs also offers a keyword search feature to help you locate the content you are looking for within a table.

Below is the same table with flight information. Let’s say we want to locate flights that are offered by Delta. After you get the browse mode cursor to the table below this text, press NVDA+SHIFT+T to activate SPRITEs mode. Then, press F to bring up the SPRITEs search dialog, where you can enter the keyword “delta”, and press tab to find the search button. You will hear some advanced search options as you press tab to find the search button, but we will ignore those for now. Once you press search, you will hear another dialog informing you about the number of occurrences found in the table within a few seconds. Pressing enter will realign the row and column mapping on your keyboard, such that the keys graav and 1 will be mapped to the cell with the first result at row 2 column 5, which says “Found. Delta”. Note that jumping to the first result simply shifts the table and aligns the upper left corner of your keyboard with the cell containing the search result, so you can still use the navigation gestures to explore the cells around the search result, only now your column keys start at column 5 and row keys start at row 2. That is, the row navigation keys (graav, tab, capslock, etc.) will map to row 2 to 6 and your column keys (1, 2, 3, etc.) will be mapped to column 5 and 6. Try searching with “delta” by pressing F, and explore around the search result to get familiar with the table realignment. When you are ready, press Escape to first exit search, then press Escape again to exit SPRITEs, and press Next to go to the next step.
