What is the purpose of "Run" , "step into" ,"step over" , "step out" , "Run till" after putting the breakpoint?

[Dark Byte]

run: continue from the breakpoint
step into: execute one instruction and follow where the instruction pointer ends up next
step over: if on a call run until after the call, else same as step into
step out: execute till the end of the current function
run till: set a 1-time breakpoint at the given address and continue

Can I also add or use a custom step? Like "execute till the value at address 0x1000 is changed"
?
If yes then how?
