Hotkey to select content of the current cell

Hotkey to select content of the current cell

is there a hot-key or a sequence of hot-keys to select the content of a
table-cell in MS-word? the cursor is within that cell.
All I found is Tab for next cells content and Shift+Tab for previous cells
content.
Different hot key pages on the web show "toolbar 32778" as hot-key.
I need this information for a VBA Macro.
