Control elements:
Search, toggle album cover on/off, radio on/off, playlist selection, jukebox mode
Volume, temporary volume

If the temporary volume is activated, the program remembers the current volume level. The volume can then be adjusted, and after a selected number of music tracks it automatically reverts to the original level.
If an hourglass is displayed whentryingto access jukebox function, it indicates that changes to the files in the music directory have been detected and it is re-reading the tags.
If you have moved back several tracks, you can return to the last track played by holding the next symbol for 1.5 seconds.

Search for music tracks

Control elements:
Exit the search, input field for the search text, clear the input field
On-screen keyboard (can be hidden with the symbol at the bottom left)

The individual search terms are separated by spaces. Tracks are listed if all entered search terms appear either in the artist name or the title.
You can select (and remove) any number of tracks from the search results. selected tracks are highlighted in yellow, and their position in the queue of the next tracks to be played is indicated by a number at the beginning of the line.
If the currently playing track is included in the search results, it will be highlighted in red and cannot be selected again.
Quitting the search process with Enter starts the first selected track immediately.

Selecting playlists

Control elements:
Exit the selection, input field for search text, clear the input field
(List of playlists)
On-screen keyboard (can be hidden with the symbol at the bottom left)

Selecting playlists is almost the same as searching for songs as described in the previous section. The most noticeable difference is the first line of the list, which contains the default playlist. Selecting this line resets all selected playlists to “not selected” and the default list will be used when you change songs next time.
The selected lists are highlighted in yellow and the list currently being played is highlighted in red.

Jukebox

Control elements:
Title strips for selection (are placed in the queue)
Page with title strips back, cancel playback or exit jukebox mode, jukebox settings, search, to play, page with title strips next

Clicking on a title strip adds the track to the queue. The queue position is displayed in the title strip. Another click removes it again.
If a cover image is displayed, it can be enlarged with a click and is then displayed for 10 seconds. Another click on the image will immediately remove the magnified image. Hold down the mouse button to freeze the image.
To exit Jukebox mode, press and hold the Cancel/X key for one second.

Control elements:
Exit settings, toggle album cover on/off, smaller title strips, larger title strips

Jukebox search

The search bar accessible from the jukebox is similar to the standard search, except the results appear as title strips and physical keyboard support is not provided. If you hide the digital keyboard, the number of search hits is displayed.

Radio

Control elements:
Search for music tracks, turn off the radio, select a radio station, jukebox mode
Volume
Previous radio station, pause, next radio station

• The radio icon turns off the radio and switches to music playback without jukebox mode. The search icon or the jukebox allow you to access the same functions as in the playback view, so you can also turn off the radio.
• The list icon takes you to the list of radio stations, where you can switch between stations and filter by station name, similar to the music search. The Enter key on the on-screen keyboard switches directly to the selected station.
• The Back and Forward buttons change the radio station.

Selection of radio stations

Control elements:
Exit the selection, input field for search text, clear the input field
(List of radio stations)
On-screen keyboard (can be hidden with the symbol at the bottom left)

• Selecting radio stations is almost identical to searching for music tracks as described above. The main difference here is that when you select a line, the radio immediately switches to the corresponding station, allowing you to quickly find a suitable program.
• The station number is displayed at the beginning of each line in the list of radio stations.
• A selected station is highlighted in yellow while the connection is being established, and the active station is highlighted in red.
• Especially for use with the “AirMouse” remote controls described below, the station list can also be accessed by pressing and holding the left mouse button, which corresponds to the OK button on the front of these remote controls. The station can then be selected using the up/down cursor keys, which (in addition to the buttons on the back) are also mapped to the navigation ring on the remote control. Instead of the usual mouse click function, the next mouse click (hence the OK button) then triggers the channel change.

Special search features

Search by year

Entering a four-digit year YYYY will list all songs from that year. If you want to search for this number in the title or artist name instead, just enter something else, like a blank.
A period of several years can be entered in the form YYYY-YYYY.
At the moment, this search is only possible with a physical keyboard because the on-screen keyboard does not yet allow the entry of numbers.

Search for abbreviated band names

To ensure that a search for abbreviated band names is also successful, a list of abbreviations is available whose filename is entered in the configuration entry SearchAbbreviations. This makes it possible, for example, that typing “CCR” also finds the songs of Creedence Clearwater Revival.

Operation by remote control

The devices sold under the name Air Mouse have proven to be practical as remote controls. These are remote control-sized devices with remote buttons and a reasonably complete keyboard on the back. A USB dongle is used for wireless connection. They are also available with backlit buttons (see picture above).
The name is derived from the way the mouse pointer is controlled using an acceleration sensor (which I think is a bit of a learning curve, but mouse control is not important for the player). They are designed for smart TVs, but they also work with computers of all kinds (Windows, MacOS or Linux on Raspberry).
The first one I bought was the Air Mouse MX3, this version has an English keyboard. I now have an Orbsmart AM-1 Pro (pictures below), which has a full German keyboard layout (Ctrl or German umlauts are occasionally helpful), works well and is equipped with a rechargeable battery, whereas the MX3 is powered by AAA batteries.

Lyrics Jukebox can (apart from the jukebox option) mainly be operated with a physical keyboard. For example, if you want to control a small Raspberry player from a distance, it makes sense to display the controls in very large characters (press K, then K+ is displayed when the large key display is switched on). The messages are then displayed as large text or scrolling text, making it possible to use the search feature from a distance of 5 meters, even on a device with a 5-inch screen.
The volume is then controlled using the cursor keys (up and down arrows). However, the volume buttons on the other side of this remote control also work, but they change the systems volume; you should therefore not use them because this setting is not saved on a read-only Raspberry.
You can switch to the previous or next track (or the next radio station) by pressing Page Up or Page Down. These commands are located on the front of both Air Mouse models (Pg + and Pg -). You can also select the radio station using the number buttons (on both sides of the remote control).
If you want to use the search feature, press F. You can then enter keywords (the cursor keys or backspace for deleting also work). You can then use the cursor keys to move down in the search results and use the space bar to select the tracks you are looking for. The currently selected line is then displayed as a large ticker and when it is selected, the color changes to yellow. Press Esc (several times) to exit the search.
