[GNC] Missing Register Right Click Options

[j a]

Hello,

I recently upgraded GnuCash from 4.13 to 5.6, and immediately noticed that
the options presented when performing right click options in a register
have been removed.

Please advise of how to implement options that were previously accessible
by right click in a register, including the following:
- sort register entries;
- filter register entries;
- jump to a different register;
- split a transaction
- schedule a transaction
