b. 344-346

composition: Op. 16, Rondo in E♭ major

..

In FE, the wavy lines next to the trill marks are short. We consider it to be an inaccuracy of notation – the need to trill throughout the entire value of the note seems to be obvious in this context – and extend the wavy lines in the main text accordingly. In GE and EE, the wavy lines are completely absent.

b. 344-346

composition: Op. 16, Rondo in E♭ major

in FE (→GE,EE)

3 long accents suggested by the editors

..

The  hairpins can only denote long accents in this context. Chopin's original markings may have been more or less extended in FE (→GE,EE).

b. 344

composition: Op. 31, Scherzo in B♭ minor

Wedge in A (→FC,FE)

Dot in GE1 & EE

No mark in GE2 (→GE3)

..

The staccato mark in A, despite its smallness, is clearly prolonged (vertically). Both Fontana in FC and the engraver of FE regarded it as a wedge. GE1 and EE changed it to a dot, which can be considered acceptable, taking into account the fact that both passage E major sections feature only dots except for this place, including in analogous b. 438 & 446. GE2 (→GE3) did not include the mark, which could easily be considered an oversight if it were not for the dot in analogous  b. 446, which was also left out.

b. 345

composition: Op. 39, Scherzo in C♯ minor

..

In EEGC and FE there is no  raising ato a2. The accidental was added in GE, which must have been done by the reviser.
