I discovered for a reason or an other TAB + G (keys combo to hide GUI) and TAB + F5 (or F6) (keys combo to force the reload of sector) didn't works on my different installations.
The game instead of process like TAB+G and TAB+F5(F6) process something like if I press separately TAB then G or TAB then F5 (F6) [so concretely TAB switch ship mode and then open ship status for the combo TAB+G and switch ship mode and take a screenshot for TAB+F5(F6)].
Don't know if it's link to the fact I rebinded TAB key to use it to switch ship mode or/and maybe cause I use French language package. I don't know all the other "hard-coded" combo to test them and see if they work or not.
