Hi,
As default behavior on browsers, when spell checker find issue, it highlights it with red underline, and right-click show fixing propositions.
On projeqtor text editor fields (managed with CK Editor) right-click only show a context menu "paste".
This is due to use of CK Editor plugin "Paste From Word". This plugin allows to copy formatted text in Work and paste it directly in Projeqtor, with formating, even with Tables.
There is a trick to get the borser fixing proposition (default browser behavior) : just hold the [CTRL] key when you right-click.
