# -only events with reminders will trigger an alarm (shown in khal as: ⏰)
11

# -snoozed events will show up again on the next run
12
+
# -dismissed events will not trigger an alarm again
13
+
# -no alarm will be triggered if the script did never run
14
+
# for the duration of an event or in TIMESPAN beforehand

# rofi: -Shift+Return toggles item selection

# -if any item is selected, "cursor" position has no effect
18

# -timeout after 60 seconds; this snoozes all events
