Description of the Issue

The very useful command Edit (menu) > Begin/End Select has no default key binding.
Suggest defaulting the currently unused Ctrl+Shift+b to this command. (NOTE: Ctrl+b might be better for this function, but it is already used in the default keymapping supplied with N++).

Usage of this command comes up frequently on the support site, for users seeking to select a lot of text without long scrolling with a keyboard or mouse selection. It would be nice to tell users to use a keycombo to start/end their selection, instead of saying "go into the Edit menu and choose Begin/End Select, then move your caret, then go back into the Edit menu and choose Begin/End Select again".
