 The secondary subtitle hold works with or without keyboard-only mode. Assign it with **Learn** on the **Show Secondary Subtitle (Hold)** row in `Alt+C`. While held, the secondary subtitle shows as if its mode were `visible`; releasing the button returns it to your chosen mode.

 **Previous Entry** and **Next Entry** move one word entry at a time in the open popup, and Mine Card then mines the selected entry. They send Yomitan's default `Alt+Up` / `Alt+Down` entry shortcuts, so they stop working if you rebind those in Yomitan's keyboard settings. If you assign them to the D-pad, click **Clear** on the **Popup Scroll (D-pad)** row too, or the D-pad will also scroll the popup.
 
+When the subtitle is split in the wrong place, a word can start in the middle of a box (in もっとハ|キ|ハキしなくちゃ, ハキハキ starts at the last character of the first box) and moving by word never reaches it. In keyboard-only mode, press `C` on the keyboard, or the **Toggle Character Navigation** button (unbound by default, under **Navigation** in `Alt+C`), to move one character at a time: the box turns orange and covers one character, and a lookup searches from that character, so Yomitan finds the longest word starting there. Press it again to go back to moving by word. It stays on until you switch it back, even after leaving keyboard-only mode.

 The media timing review and duplicate card (field grouping) dialogs have their own controller layouts, which you can change in the **Review media timing** and **Duplicate card (field grouping)** groups of `Alt+C`; see [Review media timing](/anki-integration#with-a-controller) and [Field grouping](/anki-integration#field-grouping-with-a-controller).
 
 On controllers that report the W3C standard layout, the default quit button lands on `L2` instead of `Select`, and the default pause button on `Start` instead of `L3`. The default right-stick popup jump does nothing on these controllers; click **Learn** on **Popup Jump (Stick)** and move the right stick up or down to set it. Remap anything else with `Alt+C`, which names buttons according to the layout your controller reports. All options are in [Configuration](/configuration#controller-support).
