Which keyboard would be better for a beginner?
Well those are pretty different keyboards. The YPT-220 is much better. Its really funny, before I even opened up the question and saw your question. I thought of the YPT330 or the Yamaha DGX230. I have a 230 and love it. Best of luck, you really can not go wrong anymore out there. they are all fine now a days. its mostly about preference. Are you going to be playing it through speakers or not? (This will determine if you want nice speakers on the keyboard itself) do you want light up keys. do you want the ability to connect to an amp or computer. etc. (it can get complicated but mostly any keyboard out there will work for beginners. Hope this helps.
Logitech K700 keyboard doesn't show up in /dev/input
As this is a single controller (receiver) for multiple "devices" I am suspecting you wo not get them on their own - and the mouse is taking precedence in the way the Pi is seeing them, which is typical for mixed devices in my experience. I have a similar Microsoft keyboard which behaves in exactly the same manner.They are integrated into the same unit so you cannot really test with just the keyboard, but I strongly suspect you wo not be able to get the keyboard alone to appear on the list; You should however be able to access it using the standard input stream in programming (mine works just fine with my Java coding, as well as with that of others). Without knowing the reason you need the keyboard on its own all I can suggest is using the mouse input as you have found it - it should read they keyboard portion just fine for most applications
How to clean under the keys of the keyboard?
turn it the incorrect way up and shake it. you could also get cans of air that you will stick a straw into the nozzle. once you've a vaccum purifier that has a hose connected to it that blows out air, you should use that yet be gentle with the keys, you do not could get genuine close. Or once you've an air compressor, you should use that yet back be very gentle, shop it severe off the keyboard at an attitude because it truly is sturdy. With a pc, verify you blow out the fan too, it can get very dirty
What is the best way to clean the keyboard , not just dust it ?
While the computer is off. Turn the keyboard upside down and tap it. the big stuff will fall out. Use a duster to get the rest of the small stuff. Then get some rubbing alcohol or alcohol wipes and then wipe down all the keys. If you are dedicated, pop all the keys out, and wash them in detergent. With the rest of the keybaord underneath, get an alcohol wipe and just wipe it down. Do wait until the keys are completely dry before you pop them back on. Go to your nearest office supplies store for anti-static wipes. They also have good ones for monitors too. For just alcohol wipes, you can get medi-swabs from the chemist, if you are desperate.
My laptop keyboard is really messed up?

List of keyboard and lute compositions by Johann Sebastian Bach
Keyboard and Lute Works is the topic of the fifth series of the New Bach Edition. Keyboard Works (Klavierwerke) by Johann Sebastian Bach traditionally refers to the Nos. 772 to 994, Chapter 8 in the BWV catalogue, listing compositions for a solo keyboard instrument like the harpsichord or the clavichord. Despite the fact that organ is also a keyboard instrument, and that in Bach's time the distinction was not always made whether a keyboard composition was for organ or another keyboard instrument, Wolfgang Schmieder ranged organ compositions in a separate section of the Bach-Werke-Verzeichnis (Nos. 525-771). Also other compositions for keyboard, like compositions for lute-harpsichord and fortepiano were listed outside the "Klavierwerke" range by Schmieder. Lute works are in the range 995-1000, Chapter 9 in the BWV catalogue. Bach was a prodigious talent at the keyboard, well known during his lifetime for both his technical and improvisational abilities.
Many of Bach's keyboard works started out as improvisations. Bach wrote widely for the harpsichord, producing numerous inventions, suites, fugues, partitas, overtures, as well as keyboard arrangements of concerto music by his contemporaries. The fortepiano is an instrument Bach would have encountered once, by the end of his life when it was recently invented, while visiting his son in Potsdam. The visit resulted in Das Musikalische Opfer, parts of which may have been intended for the new instrument. Several of Bach's works for keyboard were published in print in his own lifetime.
Four such publications were given the name Clavier-bung (Keyboard Practice) by the composer. Bach was not the first to use that name, for example Bach's Leipzig predecessor Johann Kuhnau had used it for two volumes published in the late 17th century. The first volume, Bach's Opus 1, was published in 1731, while the last was published a decade later. The first, second and last volume contain music written for harpsichord, while the third was written for the organ, only four duets contained in that volume ending up in the BWV 772-994 range. The Well-Tempered Clavier, a collection of forty-eight Preludes and Fugues, was not printed until half a century after Bach's death, although it had circulated in manuscript form before that.
Before the extensive rediscovery of his works in the nineteenth century, Bach was known almost exclusively through his music for the keyboard, in particular his highly influential Well-Tempered Clavier, which were regularly assigned as part of musicians' training. Composers and performers such as Ludwig van Beethoven and Camille Saint-Sans first showed off their skills as child prodigies playing the entire cycle of Bach's forty-eight Preludes and Fugues. Modern composers have continued to draw inspiration from Bach's keyboard output. Dmitri Shostakovich, for example, wrote his own set of Preludes and Fugues after the Bach model. Jazz musicians and composers, in particular, have been drawn to the contrapuntal style, harmonic expansion and rhythmic expression of Bach's compositions, especially the works for keyboard.
The first section below lists all compositions in the BWV 772-994 range, then follows a section listing other compositions for keyboard instruments, excluding the organ. After the composer's death most of his keyboard compositions, and many others, are, or were, often performed on the piano, played either directly from a score for the instruments as the composer knew them, or from a score that was a transcription for piano. The latter is sometimes needed even for harpsichord scores while for instance a composition intended for a two-manual harpsichord (like the Goldberg Variations) can present difficulties for the crossing of hands when performed on a single-keyboard instrument like the piano. Some of the transposers/arrangers of Bach's work added their own inspiration, like Busoni in his arrangement and expansion of Bach's Chromatische Fantasie und Fuge, BWV 903. The fourth section of this list refers to such transcriptions and arrangements for the piano.
