Suggest creation of Help/Keystrokes, probably to point to http://www.claws-mail.org/manual/claws-mail-manual.html#keyb_mail Better would be an on the fly generation of the keystroke list, but the link would do in the mean time. There's a fair bit of menus to slither through to find out what keystrokes are in use, and thus which aren't (more problematic). [Proving a negative.] I ran into this when trying to assign 'm' to toggle un/read, or even mark read, and failed. (Wiki article on assignable keystrokes or more info would be useful. [Beyond the keystroke info currently available.]) Then failed to see why m could't be assigned / what it was already assigned to by looking through menus. The wiki article notes "There are other key combinations which are assigned by default to menu items. We won't list these here, as they are already shown on the righthand side of the menus themselves ..." See above. Listing them (defaults) here in the article would be useful - especially if one played then wanted to go back to default, for that one keystroke only, but can't remember what it was. (Absenting the keystroke list above.) Being able to say "click Help/Keystrokes" instead would be useful (if doing so was an on the fly list). The article also notes "Furthermore, if you don't like them, these shortcuts can be changed on the fly by focusing on the menu item and pressing the desired key combination." - evidently not always true. e.g. For 'm', which is why/how I got to submitting this request. (Including wiki notes about unassignable keystrokes.) So, a few details / links towards constraints surrounding keystrokes and keystroke assignment would be useful in this part of the wiki article, as well. In the mean time, http://lists.claws-mail.org/pipermail/users/2013-June/006631.html was helpful.
