Ctrl+Y not support

[sysys]

In Windows, Ctrl+'Y' means "redo the last action performed".
PL/SQL Developer does not support this shortcut.

 

[Marco Kalter]

There is indeed no "redo last action" function in PL/SQL Developer.

In SQL Windows, redo's hot tab is Shift+Ctrl+Z, while other text editor (e.g. editplus, MS Word) and Windows use Ctrl+Y. But in SQL Windows, Ctrl+Y means delete the current line.

The "redo last undo" function is indeed assigned to Ctrl-Shift-Z by default. If you want to swap the Ctrl-Shift-Z and Ctrl-Y assignments you can do so through Tools > Preferences > Key Configuration.
