Keys on keyboard only work if shift key is pressed

In the last weeks I encountered a weird problem on my computer: Two keys i.e. the # and the 3 key only produce an input if they are pressed together with the ⇧ key.

Since I use a german Keyboard ⇧ + 3 results in § and ⇧ + # results in '. Interestingly this problem is not present on the locked screen where I can enter both keys normally. xev gives the following output:

KeymapNotify event, serial 40, synthetic NO, window 0x0,
keys:  2   16  0   0   0   0   0   0   0   0   0   0   0   0   0   0   
       0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0

    state 0x0, keycode 12 (keysym 0x33, 3), same_screen YES,
    XLookupString gives 1 bytes: (33) "3"
    XFilterEvent returns: False

And:

KeyRelease event, serial 40, synthetic NO, window 0x4800001,
    root 0x7a7, subw 0x0, time 6169284, (386,1007), root:(2306,1036),
    state 0x0, keycode 51 (keysym 0x23, numbersign), same_screen YES,
    XLookupString gives 1 bytes: (23) "#"
    XFilterEvent returns: False

For the normally working keys, I don't get the two lines with the numbers.

Any ideas on how to fix this?

The key which didn't work earlier was due to the wrong key mapping that I seemed to have entered. To solve the issue I had to reset all shortcuts.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
