In[1]:= f[x_] := x + 1
Automatically apply f to any input
In[2]:= $Post = f[#] &
Out[2]= f(#1)&+1
In[3]:= 2
Out[3]= 3
In[4]:= 67
Out[4]= 68
In[5]:= 31
Out[5]= 32
Stop applying f
In[6]:= $Post =.
In[7]:= 2
Out[7]= 2
Map f onto a list
In[8]:= f /@ {2, 67, 31}
Out[8]= {3,68,32}

Dear Friends
Let, as an example,
f[x_] := x + 1
be a function I have to calculate over and over again;
it would result useful redirecting input to avoid
typing
f[2] Enter
f[67] Enter
f[31] Enter
...
and simply make use of
2 Enter
67 Enter
31 Enter
...
Plese, can you point out a trick to perform it ?
Best Regard
