step command and icons

[PascalA]

Thanks a lot for this work !! I appreciate it very much and my pupils will appreciate it too.

I would like icons for step into and step out commands.

Using those commands through the menu is not convenient, and when I use the keybooard each time I type Ctrl+J (or Ctrl+Maj+J) a new line is inserted in the source code.

I think that for a beginner, icons are very useful and for a more advanced user, single key commands (such as f5, f6, f7) would be more efficient than commands involving 2 ou 3 keys (such as Ctrl+Maj+J).
